A soccer player horizontally kicks a ball of mass 0.608 Kilogram which is initially at rest. The player's foot is in contact with the ball for 253.1 ms. If the ball reaches a speed of 3.69 m/s in this time find:
A) Find the impulse delivered to the ball.
B) Find the average force imparted to the ball.
C) Find the acceleration of the ball as it was kicked.
