A player bounces a 0.47 kilogram soccer ball off her head, changing the velocity of the ball from vi = (8.5m/s)x + (-2.8m/s )y to vf = (6.0m/s )x + (3.6m/s )y.
Part A If the ball is in contact with the player's head for 6.7 milliseconds, find the direction of the impulse delivered to the ball?
Part B Find the magnitude of the impulse delivered to the ball?
