A uniform rod having a weight of 10 lb is pin supported atA from a roller which rides on a horizontal track.

Part A If the rod is originally at rest, and a horizontal force of F=15lb is applied to the roller, determine the acceleration of the roller. Neglect the mass of the roller and its size d in the computations. Solve the problem assuming that the roller at A is replaced by a slider block having a negligible mass. The coefficient of kinetic friction between the block and the track is ?k=0.2. Neglect the size of the block in the computations. aA=?
