A soccer ball with a mass of 0.432 kg approaches a player horizontally with a speed of 16.0 m/s. The player kicks the ball with her foot, which causes the ball to move in the opposite direction with a speed of 22.8 m/s.
(a) What magnitude of impulse (in kg · m/s) is delivered to the ball by the player? _______kg · m/s
(b) What is the direction of the impulse delivered to the ball by the player?
Opposite to the ball's initial velocity
Perpendicular to the ball's initial velocity I
n the same direction as the ball's initial velocity
The magnitude is zero.
(c) If the player's foot is in contact with the ball for 0.0600 s, what is the magnitude of the average force (in N) exerted on the player's foot by the ball? ____N
