A golf club is swung in a planar motion by a right-handed golfer (figure below). Given the initial velocity of the golf ball (v), the arm length and club length, what was the angular velocity of the left shoulder at the point of ball contact? Assume that the left arm and the club form a straight line and that the initial velocity of the ball is the same as the linear velocity of the club head at impact.
