A block of ice at 0°C whose mass initially is m = 50.0 kg slides along a horizontal surface, starting at a speed vo = 5.72 m/s and finally coming to rest after traveling a distance d = 21.37 m. Compute the mass of ice melted as a result of the friction between the block and the surface. (Assume that all the heat generated owing to friction goes into the block of ice.)
.5(M initial)V^2 = L * (Mass of ice)
a=L*(mass of ice)
The Attempt at a Solution
.5(50.0)(5.72)^2 = L *(Mass of ice)
I have all of the information I need to plug numbers into the first equation & solve for mass of ice, yet I don't have L. L is the latent heat of ice, I know that much, but what value do I use.
