Question: A rugby player runs with the ball directly toward his opponent's goal, along the positive direction of anxaxis. He can legally pass the ball to a teammate as long as the ball's velocity relative to the field does not have a positivexcomponent. Suppose the player runs at speed 4.0 m/s relative to the field while he passes the ball with velocity v(BP) relative to himself. Ifhas magnitude 6.5 m/s, what is the smallest angle it can have (relative to the positive direction of thexaxis) for the pass to be legal?
