The block of mass m2 is sliding along a horizontal surface with the coefficient of kinetic friction µ2 between the surface and the block. A smaller block of mass mi is sliding on the vertical surface of the larger block. The coefficient of kinetic friction between the larger block and the smaller block is μ1. The two blocks are connected by a massless string of constant length, which passes over three massless pulleys, as illustrated in the figure. a) Draw a free-body diagram of the system. m2 b) Determine the acceleration of the larger block (m2). m1
