steel block of mass m is given a push so that it initially slides along a horizontal, steel track of mass M with speed v_0. The block and the track have the same specific heat c. After the initial push, the only forces acting on the block are its weight, a normal force from the track, and friction with the track (coefficient of kinetic friction μ_k). The block travels some distance before coming to rest. Both the block and the track are initially at a temperature T_0 and both end up at a temperature T_1 after the block has come to rest. You may assume that no heat leaves the block + track system and the the only source of heat to increase the temperature
