A uniform rod having weight W is pin-supported at A from a roller which rides on horizontal track. Assume that the roller at A is replaced by a slider block having a negligible mass. If the rod is initially at rest, and a horizontal force F is applied to the slider, determine the slider’s acceleration. The coefficient of kinetic friction between the block and the track is μ_k. Neglect the dimension d and the size of the block in the computations.
