Homework Help: physics

Posted by mike on Monday, February 15, 2010 at 6:17pm.

A 2.5 kg block of ice at a temperature of 0.0 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 1.0 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?

(Our teacher doesn't teach us, plus I'm not really geared towards physics. Any help provided would be appreciated.)
