A toy car is allowed to roll down a ramp during an experiment. While it is on the ramp, gravity acts on the car as an unbalanced force. Which of the following graphs best illustrates the car’s velocity as a function of time while it is on the ramp?

Answers

Answer 1

Answer:

When an unbalanced force acts on an object, the motion of the object is changed. If the object is at rest, the force makes it move. If the object is in motion, the force changes its velocity. Any change in velocity is acceleration

Identify whether the ocean waves transferred more or less energy in the morning than in the afternoon.
Write your answer in complete sentences.

Answer:

They transfered more energy in the morning.

Explanation:

This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with  the waves. They have more energy, so they can crash aganst the shore more!

Ranjana has average velocity 3.2 m/s
How long does she take to cover a displacement
of 256 m

Answers

Answer:

t= 80 seonds

Explanation:

Given that,

The average velocity of Ranjana, v = 3.2 m/s

We need to find how long does she take to cover a displacement  of 256 m. Let she takes t time.

We know that,

Average speed = distance/time

So,

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{256\ m}{3.2\ m/s}\\\\t=80\ s[/tex]

So, she will take 80 seconds to cover a displacement of 256 m.

An eagle flying 10 meters per second swoops down to the ground to catch a snake speed velocity or acceleration

Answers

Answer:

Velocity because it has both magnitude (10m/s) and direction (to the ground).

Explanation:

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

[tex]Velocity = \frac{distance}{time}[/tex]

In this scenario, an eagle flying 10 meters per second swoops down to the ground to catch a snake. Therefore, this is an example of velocity.

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)

Answers

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.

what is the formula for acceleration?

Answers

Answer:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
