A 5.5 kg block of ice at -1.5 C slides on a horizontal surface witha coefficient of kinetic friction equal to 0.062. The initial speedof the block is 6.9 m/s and its final speed is 5.5 m/s. Assumingthat all the energy dissipated by kinetic friction goes intomelting a small mass m of the ice, and the rest of the ice blockremains -1.5C, determine the value of m.
