A 5kg box is sliding down a ramp with a rough surface as seen below. The height of the ramp is 20m and the distance the box trav
els down the ramp (from A to B) is 15m. At point A the velocity of the box is 8 m/s. If the velocity at point B is 3m/s, what was the impulse caused by friction? If the force of friction is 5N, how long did it take the box to slide the 15 m?
