Answer to Question #40934 in Mechanics | Relativity for alzahra
A 2-kg metal block slides on a rough horizontal surface inside an insulated box. After
sliding a distance of 500.0 m, its temperature increased by 2.00 0C. Assuming that all
heat generated by frictional heating goes into the metal block, and the metal has a
specific heat capacity of 0.150 cal/(g.0C), find:
(i) How much work (heat Q) does the force of friction does on the block?
(ii) What is the coefficient of kinetic friction between the block and the surface?
