A soccer player runs up behind a 0.450-kg soccer ball traveling at 3.20 m/s and kicks it in the same direction as it is moving, increasing its speed to 12.8 m/s.
(a) What is the change in the magnitude of the ball’s momentum?
(b) What magnitude impulse did the soccer player deliver to the ball?
(c) What magnitude impulse would be required to kick the ball in the opposite direction at 12.8 m/s instead?
