Physics - Heat & Thermo Question with Solution | TestHub

A body of mass $25\mathrm{kg}$ is dragged on a rough horizontal floor for one hour with a speed of 2km/h. The coefficient of friction between the body and the surface in contact is 0.5 and half the heat produced is absorbed by the body. If specific heat of body is $0.1\mathrm{cal}$ ${\mathrm{g}}^{-1}$ (${}^{\circ }$C)${}^{-1}$, then the rise in temperature of body is
