The arrows show the direction of rotation of the merry-go-round, which moves with a constant speed, moves with a constant speed causing a shift of 45? . assuming a child sitting in the center attempts to throw the ball directly to child d, which child will likely catch the ball?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
