a 75kg skater is travelling at 15m/s stops suddenly on the ice. If the ice is at 0 degrees and it is assumed that all of the skaters energy is converted to heat, how much ice does he melt? (latent heat of fusion for water is 3.3x10^5 J/kg)

  1. Assume all of the kinetic energy,
    (1/2) M V^2 = 8438 J, is used to melt the ice. Divide that energy by the latent heat of fusion, 3.3x10^5 J/kg. The answer will be in kg.
