A 3 kg block initially traveling at 5 m/s collides with a 1 kg block (initially at rest) sitting near the base of a hill. Assuming a perfectly inelastic collision, how high up the hill do the two blocks slide after the collision?
A small, 300 g cart is moving at 1.60 m/s on an air track when it collides with a larger, 1.00 kg cart at rest. After the collision, the small cart recoils at 0.890 m/s.
A worker stands still on a roof sloped at an angle of 21° above the horizontal. He is prevented from slipping by a static frictional force of 400 N. Find out the mass of the worker.
