Just before it is struck by a racket, a tennis ball weighing 0.560 N has a velocity of (20.0m/s)ı^−(4.0m/s)ȷ^(20.0m/s)ı^−( 4.0m/s)ȷ^. During the 3.00 ms that the racket and ball are in contact, the net force on the ball is constant and equal to −(380N)ı^+(110N)ȷ^−(380N)ı^+(110N)ȷ ^. What are the x- and y-components (a) of the impulse of the net force applied to the ball; (b) of the final velocity of the ball?
