Physics

A 60.0 kg person running at an initial speed of 4.50 m/s jumpsonto a 120 kg cart that is initially at rest. The person slides onthe cart's top surface and finally comes to rest relative to thecart. The coefficient of kinetic friction between the person andthe cart is 0.320. Friction between the cart and the ground can beneglected.

a.Find the final speed of the person and cart relative to theground.

b.For how long does the frictional force act on the person?

c.Determine the magnitude of the displacement of the personrelative to the ground while he is slipping on the cart.

d. Determine the magnitude of the displacement of the cartrelative to the ground while the person is slipping on thecart.
