An 8.62 kg block of ice at 0 ?C is sliding on a rough horizontal icehouse floor (also at 0 ?C) at 15.7 m/s . Assume that half of any heat generated goes into the floor and the rest goes into the ice. A) How much ice melts after the speed of the ice has been reduced to 10.4 m/s ? B) What is the maximum amount of ice that will melt?

    A block of ice at 0oC whose mass initially is m = 42.1 kg slides along a horizontal surface, starting at a speed v0 = 2.35 m/s and finally coming to rest after traveling a distance d = 2.93 m. Compute the mass of ice melted as a result of the friction between the block and the surface. (Assume that all the heat generated owing to friction goes into the block of ice.)
