A small lead sphere of mass 25 g is attached to the origin by a thin rod of length 74 cm and negligible mass. The rod pivots about the z axis in the xy plane. A constant force of 22 N in the y direction acts on the sphere. (a) Considering the sphere to be a particle, what is the rotational inertia about the origin? (b) If the rod makes an angle of 40° with the positive x axis, find the angular acceleration of the rod.
