Shown below are a pair of blocks connected over a 40 kg solid cylinder - (1/2 = {MR ² ) pulley. Rope feeds over the pulley without slipping. The block on the table is initially moving to the left and slides 8.2 m before coming to rest. What is the coefficient of kinetic friction between the the block and the table?

Challenge: Repeat the calculation with everything being the same except the table is inclined 25° above horizontal and the block slides only 6.2 m.
