A 5.5-kg block of ice a t −1.5 “C slides on a horizontal surface with a coefficient of kinetic friction equal to 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 tha t the rest of the ice block remains at −1.5 °C, determine the value of m.
