A player bounces a 0.46-kg soccer ball off her head, changing the velocity of the ball from v⃗ i = (8.4 m/s )x^ + ( -2.3 m/s )y^ to v⃗ f = (5.9 m/s )x^ + (3.0 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?

What is the magnitude of the impulse delivered to the ball?
