Multiple Choice
A 2.00-kg metal block slides on a rough, horizontal surface inside an insulated pipe. After sliding a distance of 500.0 m, its temperature is increased by 2.00 °C. Note: Assume that all of the heat generated by frictional heating goes into the metal block. For this metal, the specific heat capacity is 0.150 cal/(g · C°) . 
-How much work does the force of friction do on the block?
A) zero joules
B) 300 J
C) -300 J
D) 2510 J
E) -2510 J
