Dear your question is under-progress, it would be available to you as soon as it completes within next few minutes.
Since the snow must melt, it goes through a phase change (occurring at 0°C), so the energy that must be added to convert a mass of snow into liquid water at 0°C is : Q = mL(f) = (1.00kg)(3.33 x 10^5J/kg) = 3.33 x 10^5J The force of kinetic friction is : f(k) = μ(k)mg The work done by friction when the skier moves through a displacement Δx is : |W(f)|= f(k)Δx If all the work done by friction is added to the snow in the form of internal energy, then the distance the skier must move through to melt 1.0kg of snow is : |W(f)| = f(k)Δx = Q Δx = Q / μ(k)mg = 3.33 x 10^5J / (0.22 x 78kg x 9.8m/s²) = 1980 m
