A rugby player runs with the ball directly toward his opponent's goal, along the positive direction of thex-axis. He can legally pass the ball to a teammate as long as the ball's velocity relative to the field does not have a positive x component. Suppose the player runs at speed 4.00 m/s relative to the field while he passes the ball with velocity xrelative to himself. If xhas magnitude 6.0 m/s, what is the smallest angle it can have (relative to the positive direction of thexaxis) for the pass to be legal?
