A block of ice at 0°C whose mass initially is m = 48.4 kg slides along a horizontal surface, starting at a speed vo = 4.91 m/s and finally coming to rest after traveling a distance d = 12.28 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.)

Initial KE+ initial PE= final KE+finalPE+heat released
calculate heat released, initial/final PE are equal.
Now use that heat
heat= mass*heatfusion calculate mass melted.
