When kicking a soccerball, a player rotates her left leg about her hip joint. Treat the effect of air resistance to be negligible and the clockwise direction of rotation to be positive. Include units as appropriate below. (a) If the speed of her shoe is 34.0 m/s and her hip joint is 1.05 m from the tip of her shoe, what is the angular speed of the shoe tip as seen from her left? = لا (b) Her shoe is in contact with the initially stationary 0.50 kg soccerball for 20.0 ms. What is the magnitude of the average force applied to the soccerball to give it a speed of 20 m/s? Fav = (c) If she kicks the ball as described in part (b) what is the maximum range of the soccerball on level ground? R= When kicking a soccerball, a player rotates her left leg about her hip joint.
