Two ice skaters, Paula and Ricardo, initially at rest, push off from each other. Ricardo weighs more than Paula. Part A Which skater, if either, has the greater momentum after the push-off? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right. zero non-zero Submit increases decreases remains the same a larger magnitude momentum than Paula a smaller magnitude momentum than Paula the same magnitude momentum as Paula Request Answer Part B Complete previous part(s) Initially, the total momentum of the skaters is the total momentum Thereforé, Ricardo has since they are at rest. After after the pur

Two frictionless carts collide with each other on a level surface. Cart A has a mass that is several times smaller than the mass of Cart B. Read the following statements about the time during the collision of the carts and select ALL answers that apply. A. Cart A has a larger magnitude acceleration than Cart B during the collision B. Cart A exerts the same amount of force on Cart B that Cart B exerts on Cart A C. Cart A exerts more force on Cart B than Cart B exerts on Cart A D. Cart A has a smaller magnitude acceleration than Cart B during the collision E. Cart A has the same magnitude acceleration as Cart B during the collision

Part A.) find the magnitude pi of the total inital momentum of the two block shaten express four answer numerically  Part B.) find vf the magnitude of the final velocity of the two block system express answer numerically  Part c.) what is the change in k =kfinal -kinital in the two block systems kinetic energy due to the collision express your answer numerically in joules

Block X Block Y VXY M M Figure 2. After the collision Block X slides along a horizontal surface with a speed tx toward block Y that is initially at rest, as shown in Figure 1. After block X collides with block Y, the two blocks remain stuck together and travel at a velocity of thy as shown in Figure 2. Frictional forces are considered to be negligible. Which of the following claims is correct regarding the momentum of the system containing only block X and the system that contains block X and block Y? A The system containing block X is an open system, and the system of both blocks is an open system. B The system containing block X is an open system, and the system of both blocks is a closed system. © D The system containing block X is a closed system, and the system of both blocks is an open system. The system containing block X is a closed system, and the system of both blocks is a closed system. ? 。 口
