A 200-Kg Metal Block Slides on a Rough, Horizontal Surface Inside

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°) .
-What is the coefficient of sliding friction between the block and the surface?

A) zero
B) 0.061
C) 0.100
D) 0.256
E) 0.299
