A block of mass 2.20kg is accelerated across a rough surface by a light cord passing over a small pulley. The tension T in the cord is maintained at 10.0N, and the pulley is .100m above the top of the block. The coefficient of kinetic friction is .400. a) Determine the acceleration of the block when x=.400m b) Describe the general behavior of the acceleration as the block slides from a location where x is large to x=0. c) Find the maximum value of the acceleration and the position x for which it occurs. d)Find the value of x for which acceleration is zero
