3. A contestant in a winter sporting event pushes a 45.0-kg block of ice across a frozen lake as shown below. F a) Using that the kinetic coefficient of friction of ice on ice is 0.03, calculate the work done by the fric tion if the contestant keeps pushing the block for 100 m. b) If all the energy dissipated by the friction was used to melt the bottom layer of the ice block, which was the percentage of the whole block melted during the total displacement?
