A copper block with a mass 1.82 kg is given an initial speed of 3.5 m/s on a rough horizontal surface. Because of friction, the block finally comes to rest. Assume that 77.4 % of the initial kinetic energy is absorbed by the block in form of heat, what is the change in temperature (in - do not enter units) of the block? Data: cCu=387
