A 2.5 kg block of ice at a temperature of 0C and an initial speed of 5.7 m/s slides across a level floor. If 3.3*10^5 J are required to melt 1.0 kg of ice, how much ice melts, assuming that the initial kinetic energy of the ice block id entirely converted to the ice's internal energy?

Physics 
bobpursley,
initial KE= heat released
1/2 2.5*5.7^2=heat released.
heat released=massicemelted*3.3E5J/kg
solve for massicemelted
