A 40.3-kg block of ice at 0 °C is sliding on a horizontal surface. The initial speed of the ice is 9.50 m/s and the final speed is 3.90 m/s. Suppose that the part of the block that melts has a very small mass and that all the heat generated with kinetic friction goes into the block of ice, and decide the mass of ice that melts into water at 0 °C.
