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