A 2.5 kg block of ice at a temperature of zero degrees celcius and an initial speed of 5.7 m/s slides across a level floor. If 3.3 x 10^{5}J are required to melt 1 kg of ice, how much ice melts, assuming that the initial kinetic energy of the ice block is entirely converted to the ice's internal energy?

2. Relevant equations

I think I need to use PE + KE + U = 0

3. The attempt at a solution

I have no idea where to even begin :(
