Just before it is struck by a racket, a tennis ball weighing 0.560 N
has a velocity of (20.0m/s)i^−(4.0m/s)j^
. 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)i^+(110N)j^.
What is the x
-component of the impulse of the net force applied to the ball?
What is the y
-component of the impulse of the net force applied to the ball?
What is the x
-component of the final velocity of the ball?
What is the y
-component of the final velocity of the ball?
