WBJEE 2020 Physics Solved Paper

A metallic block of mass 20 kg is dragged with a uniform velocity of 0.5 ms‌−1 on a horizontal table for 2.1s. The co-efficient of static friction between the block and the table is 0.10. What will be the maximum possible rise in temperature of the metal block if the specific heat of the block is 0.1 C.G.S unit ? Assume g = 10 ms‌−2 uniform rise in temperature throughout the whole block. [Ignore absorption of heat by the table]
