The uniform thin rod AB couples the slider A, which moves along a frictionless guide, to the wheel B, which rolls without slip over a horizontal surface.

Figure P7.39

Assuming that A and B have negligible mass, that the mass of AB is mAB, and that the system is released from rest at the angle θ, determine, immediately after release, the angular acceleration of the rod AB, the acceleration of the center of the wheel at B, and the angular acceleration of the wheel.
