For the winter festival, a sculptor creates a 20-kg statue of a skier made of ice at 0oC. To show off the statue's stability, the sculptor hires someone to repeatedly slide the statue down a plane 8 m long and inclined at 30o. Unfortunately, the sculptor forgot about the thermal energy produced by friction. If the coefficient of sliding friction between the ice and the plane is 0.05, how much ice melts due to the friction on the first run? (Assume that all the mechanical energy lost goes into melting the ice.)
