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