Question

A force of 500 N acts on a rocket for 600 s, causing the rocket's velocity to increase. By how much does the rocket's momentum increase?

Please give detailed answer and explanation​

Answer 1

The change in momentum of an object is equal to the impulse applied to it. Impulse is the product of force and time, or J = FΔt.

In this case, the force acting on the rocket is 500 N, and the time it is applied is 600 s, so the impulse is:

J = FΔt = (500 N) * (600 s) = 300000 Ns

The impulse applied to the rocket causes a change in momentum, which is given by the formula:

Δp = J

So the change in momentum of the rocket is 300000 Ns.
