A player bounces a 0.44-kg soccer ball off her head, changing the velocity of the ball from vi = (8.3 m/s )x^ + ( -2.3 m/s )y^ to vf = (5.1 m/s )x^ + (3.5 m/s )y^. If the ball is in contact with the player's head for 6.7 ms, what is the direction of the impulse delivered to the ball? Give answer in degrees from + x-axis. What is the magnitude of the impulse delivered to the ball?
