During the last 0.05 seconds of a golfer's swing (between t and t) he rotates his wrists to increase the angular velocity of the golf club. During this phase the angular velocity increases from 10 rad/s up to 25 rad/s at the moment of ball impact. Assume that the shaft of the club has no mass, but the head has a mass of m=0.2 kg which is 1 m away from the axis of rotation at the wrists. Calculate the wrist torque required to produce this angular acceleration of the club. Hint: I = m* r. t
