A 60 . 0 k g person moving at an initial speed of 6 . 00 m s jumps horizontally onto a 180 . k g cart (Fig. 3). The person slides on the cart’s top surface and finally comes to rest relative to the cart. The coefficient of kinetic friction between the person and the cart is μ k = 0 . 400 . Friction between the cart and ground and air resistance can be ignored. If the final velocity of the person and the cart is 2 . 40 m s , (a) what is the initial velocity of the cart? (b) What are the direction and magnitude of the impulse on the person and the direction and magnitude of the impulse on the cart? (c) What is the distance that the person slides on the cart? (d) What is the distance that the cart moves on the ground while the person is sliding? (e) What is the change of kinetic energy in the system consisting of the person and the cart? fig3_q13_t3.jpg
