A $2\mathrm{.}00-$kg metal block slides on a rough, horizontal surface inside an insulated pipe.$$After sliding a distance of $500\mathrm{.}0$ m$,$ its temperature is increased by $2\mathrm{.}00$C$.$Note: Assume that all of the heat generated by frictional heating goes into the metal block.$$For this metal, the specific heat capacity is $0\mathrm{.}150$ cal$/($g $$ C$).(1$cal $=4\mathrm{.}186$ J$)$
