A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles
together. What is the final velocity of the two vehicles?
(Please show work)
Answer:
50 x 3000 = 150000/4000 = 37.5
37.5 I think.
Explanation:
Hope this helps!
A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles together, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.
We may use the concept of conservation of momentum to calculate the final velocity of the two vehicles after the collision.
The total initial momentum (P_initial) is given by:
P_initial = (mass of truck) * (initial velocity of truck) + (mass of car) * (initial velocity of car)
P_initial = (3000) * (50) + (1000) * (0)
The velocity:
Vt = 50 * (1000/3600) = 13.9 m/s
Vc = 0 = 0 m/s
P_initial = (3000) * (13.9) + (1000) * (0 )
P_initial = 41700 kg·m/s
P_initial = P_final
41700 kg·m/s = (3000 kg + 1000 kg) * Vf
41700 kg·m/s = 4000 kg * Vf
Now Vf:
Vf = 41700 kg·m/s / 4000 kg
Vf ≈ 10.43 m/s
Therefore, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.

in what way is Speed related to Kinetic Energy?
Answer:
Explanation:
In order to find kinetic energy, you need information about the velocity. Speed is the magnitude of the velocity.
Kinetic energy is 1/2mv^2
m being mass
v being velocity
The kinetic energy of an object is directly proportional to the speed of the object. If we double the speed of the object then the kinetic energy of the object will increase by a factor of four or four times.
What is Kinetic energy?Kinetic energy is the energy which is present in an object which has because of its motion. If we want to accelerate an object, then we must apply the force of some magnitude. Applying a force, requires us to do some work. After the work has been done, then the energy has been transferred to the object, and the object will be moving with a new constant speed.
Kinetic energy is directly proportional to the mass of the object and to the square of its speed or velocity:
K.E. = 1/2 m × v²
If the mass has the units of kilograms and the velocity of meters per second, then the kinetic energy has units of kilograms-meters squared per second squared.

3. A 6 kg block moving to the right at 4 m/s collides with and sticks to a stationary block of unknown mass. If the two blocks move off to the right at 3 m/s, what was the mass of the stationary block?
Answer: 2kg
Explanation:
This problem is a textbook conservation of momentum problem. The intial momentum is equal to the final momentum. For the initial state of each block, only the first one was moving. Then they both combine to move together.
Pi = Pf
with p = mv
(6kg)*(4m/s) = (6kg+xkg)(3m/s)
Let x equal the unknown mass of block 2
24 = 18 + 3x
6 = 3x
x = 2kg

When water waves meet, they can combine to form new waves. In constructive waves, a ________ amplitude wave is formed. In destructive waves, a wave with a __________ amplitude is formed. A) greater, smaller B) smaller, greater C) smaller, smaller D) greater, greater
Answer:
In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed. (option A)
Explanation:
Interference is called the superposition or sum of two or more waves. Depending mainly on the wavelengths, amplitudes and the relative distance between them, there are two types of interference: constructive or destructive.
Constructive interference occurs when there are two waves of identical or similar frequency (both have motions equal to an even number of similar wavelengths) and overlap the peak of one with the peak of the other. These effects add together and make a wave of greater amplitude. All of this is possible because the waves were in the same phase in the beginning (in the same position).
Destructive interference occurs in the opposite case to constructive. When the crest of one wave overlaps the valley of the other, they cancel out since they are in different phases when they overlap (they were in different positions). That is, as in the case of constructive waves they were added, in the case of destructive waves they cancel out (subtract).
So, In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed.

Define potential energy (PE)
Answer:
Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system.
This form of energy has the potential to change the state of other objects around it, for example, the configuration or motion.
Various forms of energy can be grouped as potential energy.
Each of these forms is associated with a particular kind of force acting in conjunction with some physical property of matter (such as mass, charge, elasticity, temperature etc).
For example, gravitational potential energy is associated with the gravitational force acting on object's mass; elastic potential energy with the elastic force (ultimately electromagnetic force) acting on the elasticity of a deformed object; electrical potential energy with the coulombic force; strong nuclear force or weak nuclear force acting on the electric charge on the object; chemical potential energy, with the chemical potential of a particular atomic or molecular configuration acting on the atomic/molecular structure of the chemical substance that constitutes the object; thermal potential energy with the electromagnetic force in conjunction with the temperature of the object.
For an example of gravitational potential energy, consider a book placed on top of a table.
To raise the book from the floor to the table, work must be done, and energy supplied. (If the book is lifted by a person then this is provided by the chemical energy obtained from that person's food and then stored in the chemicals of the body.) Assuming perfect efficiency (no energy losses), the energy supplied to lift the book is exactly the same as the increase in the book's gravitational potential energy.
The book's potential energy can be released by knocking it off the table.
As the book falls, its potential energy is converted to kinetic energy.
When the book hits the floor this kinetic energy is converted into heat and sound by the impact.
Explanation:
Answer:
potential energy is basically stored energy
Explanation:
1. Two magnets are placed on a table, and they immediately move to attach to each other. Which statement is correct about the energies in the system?
Kinetic energy is at its peak when the magnets are first released, then it decreases steadily. Energy stored in the magnetic field becomes zero.
The kinetic energy of the system is derived from the thermal energy created by increased velocity. Energy stored in the magnetic field does not change.
Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.
The velocity and kinetic energy of the system increase as the energy stored in the magnetic field increases.

The energy stored in the magnetic field does not change.
The energy stored in the magnetic field decreases.
4. Two donut-shaped magnets are stacked on top of each other with a wooden dowel in the center. The south poles of the magnets are facing each other. Once the upper magnet is released, it accelerates downward and stops 1 cm above the lower magnet. How does the energy stored in the magnetic field change?
All of the energy stored is converted into kinetic, thermal, and gravitational energy.
Some of the energy stored is converted into kinetic, thermal, and gravitational energy.
All of the energy stored is converted into kinetic and thermal energy.
Some of the energy stored is converted into kinetic and thermal energy.
According to the law of conservation of energy, energy can neither be created nor destroyed but is transformed from one form to another.
1) The statement that is true about the magnets involved is that; "kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases."
2) In the second question, the statement that is correct about the energies of the system is that the energy stored in the system is converted to kinetic energy.
3) When a magnet is moved close to a rubber band, the energy stored in the magnetic field does not change.
4) In the fourth question, some of the energy stored is converted into kinetic, thermal, and gravitational energy.

Se usa una bombona de He para inflar globos, de volumen 15L con una presión de 200 atm. Si los globos tienen un volumen de 1.5L y presión de 770mmHg. ¿Cuántos globos se pueden llenar?
Answer:
La cantidad de globos llenos es de aproximadamente 1.974 globos
Explanation:
Los parámetros dados son;
El gas utilizado para inflar el globo = Él
El volumen del gas He, V₁ = 15 L
La presión del gas He, P₁ = 200 atm = 20,265,000 Pa
El volumen de cada globo = 1,5 L
La presión del He dentro del globo, P₂ = 770 mmHg = 102,641 Pa
Sea 'V₂', que represente el volumen total que el gas ocupa en todos los globos, y 'x', que represente el número de globos;
Por lo tanto, tenemos;
1,5 · x = V₂
Según la ley de Boyle, tenemos;
P₁ · V₁ = P₂ · V₂
∴ V₂ = P₁ · V₁ / (P₂)
Al introducir los valores conocidos, obtenemos;
V₂ = 20,265,000 Pa × 15 L / (102,641 Pa) = 2,961.53548 L
1,5 L × x = V₂
∴ 1,5 L × x = 2,961,53548 L
x = 2,961.53548 L / (1.5 L) = 1,974.35699 redondeamos hacia abajo para obtener un número entero de globos de la siguiente manera;
El número de globos, x ≈ 1,974 globos.
