Question

Troy pushes on a car for 20 seconds, during which he applies an impulse of 3000 kg⋅m/s. What force does he apply to the car?

1) 3000 N
2) 0.0067 N
3) 60,000 N
4) 150 N

Answer 1

The force applied by Troy to the car is calculated by dividing the impulse (3000 kg⋅m/s) by the time (20 seconds), yielding a force of 150 N.

Step-by-step explanation:

The question is asking us to calculate the force Troy applies to the car given that he exerts an impulse of 3000 kg⋅m/s over a period of 20 seconds. Impulse is the product of force and the time over which the force is applied. Therefore, we can find the force by dividing the impulse by the time.

To find the force applied by Troy, we use the formula: Force = Impulse / Time.

Here, we have an impulse of 3000 kg⋅m/s and a time of 20 seconds. Calculating the force gives us:

Force = 3000 kg⋅m/s / 20 s = 150 N.

So, the correct answer is 150 N, which means option 4) 150 N is the correct choice.
