The three air cartsshown in the figure have masses, reading from left to right, ofm, 2m, and 4m, respectively. Initially, the cart on theright is at rest, whereas the other two carts are moving to theright with a speed v_0. All carts are equipped with putty bumpers that give completely inelastic collisions.
