A golf club can roughly be modeled as a sphere attached to the end of a thin rod. The figure below depicts the circular path the club makes as Rory starts from the top of his swing (where the club is temporarily at rest) until it connects with the ball at the bottom of the swing. 40 thin rod phere a) Model the club as a sphere of radius R attached to thin rod of length L. Assume the thin rod and the sphere to have the same mass, M. Derive an expression for the moment of inertia for the club in terms of R, L, and M. b) Let M = 150 g. L- 0.9 m, and R-4 cm. If Rory achieves a constant angular acceleration of 344 rad/s2, what is the torque he applied to the club throughout the swing? Edit
