When kicking a football, the kicker rotates his leg about the hip joint.   a) If the velocity of the tip of the kicker’s shoe is 31 m/s and the hip joint is 1.03 meters from the tip of the shoe, what is the shoe tip’s angular velocity in degrees/sec? b)The shoe is in contact with the initially stationary 490 gram football for 24 ms. What average force is exerted on the football to give it a velocity of 18 m/s when it begins traveling in air after leaving the foot?
