A soccer player bounces a ball off of her head, changing the velocity of the ball. She changes the x component of the velocity of the ball from vix = 8.70m/s to vfx = 5.10m/s and the y component from v1y = -4.00m/s to vfy = 2.70 m/s. If the ball has a mass of 0.45kg and is in contact with the players head for 7.10ms, determine the following. Assume that the positive x axis is to the right and positive y axis is up. A. Direction of the impulse delivered to the ball in degrees counterclockwise from the x axis. B. Magnitude of the impulse delivered to the ball in kg * m/s.

Question
A soccer player bounces a ball off of her head, changing the velocity of the ball. She changes the x component of the velocity of the ball from vix = 8.70m/s to vfx = 5.10m/s and the y component from v1y = -4.00m/s to vfy = 2.70 m/s. If the ball has a mass of 0.45kg and is in contact with the players head for 7.10ms, determine the following. Assume that the positive x axis is to the right and positive y axis is up.
A. Direction of the impulse delivered to the ball in degrees counterclockwise from the x axis.
B. Magnitude of the impulse delivered to the ball in kg * m/s.
