2. an iceskater of mass 100 kg starts to glide at 10 m/s and comes to rest. how much ice is melted? assume that half the heat generated by friction is absorbed by the ice and that the ice is at its melting point.
Heat from skater* .5 = Lf*massice.
1/2 massskater*100*.5= Lf*massicemelted.
Put lf in units of joules/kg
