A heavy metal block is dragged along a rough horizontal surface at a constant speed of 20 km/hr. The coefficient of friction between the block and the surface is 0.6. The block is made of a material whose specific heat is $$0.1\ \text{cal g}^{-1}\ ^\circ\text{C}^{-1}$$ and absorbs 25 percent of heat generated due to friction. If the block is dragged for 10 min, the rise in temperature of the block is about (take $$g = 10\ \text{ms}^{-2}$$)
