Question

Two identical carts labeled A and B are initially resting on an air track. The coordinate system for describing the system is shown. The cart on the right, cart B is given a push to the left and is released. The clock is then started. At t = 0, cart B moves in the direction shown with a speed v_0. They hit and stick to each other. The graphs below describe some of the variables associated with the motion as a function of time. For the experiment described and for each item in the list below, identify which graph is a possible display of that variable as a function of time assuming a proper scale. "The system" refers to carts A and B together. the momentum of cart B the force on cart A the total momentum of the system the kinetic energy of cart B the total kinetic energy of the system

Explanation / Answer

a.Momentum of Cart B --- 3

b.Force on Cart A -------- 7

c.Total Momentum of system --- 5

d.KE of cart B ------------------ 2

e. Total KE of System-------- 4
