Rod AB has mass m and length l, there is no friction between the rod and the inclined surface, and cos(beta)=4/5. The rod is released from rest at an initial angle theta from the vertical. If the initial value of theta if theta=beta, then immediately after the rod is released: (a) the normal force acting on the rod at A is? (b) the magnitude of the acceleration of the center of mass is? If the initial value of theta is theta=0, then immediately after the rod is released: (c) the normal force acting on the rod at A is? (d) the magnitude of the angular acceleration is?
