A 5.5kg block of ice at -1.5 degree C slides on a horizontal surface with a coefficient of kinetics friction equal to 0.062. The intial speed of the block is 6.9m/s and its final speed is 5.5m/s. Assuming that all the energy dissipated by kinetic friction goes into melting a small mass, m, of the ice, and that the rest of the ice block remains at -1.5 degree C, determine the value of m.
