Compare the carts’ (a) kinetic energies and (b) momentum magnitudes after covering the distance d, and indicate your reasoning.Two Pushed Boxes: Equal Time A lighter and heavier box are at rest on a frictionless surface. The same force pushes on each box for 1 s. Which box has the larger change in momentum after pushing? Lighter Heavier Insufficient Information Same Submit Answer Tries 0/2 Which box has the larger change in kinetic energy after pushing? Remember, the change in kinetic energy is equal to the work done. Insufficient Information Same Lighter HeavierA volleyball player starts a serve by throwing the ball vertically upward. The 240g volleyball comes to rest at its maximum height. The server then hits it and exerts an average horizontal force of magnitude 6.2 N on the ball. Determine the speed of the ball after the player hits it if the average force is exerted on the ball for 600 ms.
