Q. A player bounces a 0.47 kg soccer ball off her head, changing the velocity of the ball from i = (9.2 m/s) + (-2.7 m/s) to f = (6.1 m/s) + (5.5 m/s). The ball is in contact with the player's head for 6.70ms.
(a) What is the direction of the impulse delivered to ball?
(b) What is the magnitude of the impulse delivered to ball?
