A 70 g metal block moving at 200 cm/s slides

A 70 g metal block moving at 200 cm/s slides across a tabletop a distance of 83 cm before it comes to rest. Assuming 75% of the thermal energy developed by friction goes into the block, how much does the temperature of the block rise? For the metal, c = 0.106 cal/g deg c. The answer is 0.0034 deg c. Show all steps to the solution.
