A 0.15 kg ball hits a wall with a velocity of (6.00 m/s) i + (6.50 m/s) j + (5.50 m/s) k. It rebounds from the wall with a velocity of (2.00 m/s) i + (3.50 m/s) j + (-3.20 m/s) k

a) What is the change in the ball's momentum?
(__i +__j +__k ) kg · m/s

b) What is the impulse on the ball?
(__i +__j +__k ) N · s

(c) What is the impulse on the wall?
(__i +__j +__k ) N · s
