Please answer this Physics question.

Question 6 (1 point] A (7.00x10"1)kg block of ice at 000C breaks off from a glacier, slides along the frictionless ice to the ground from a height of 2.43 m, and then slides along a horizontal surface consisting of gravel and dirt. Find how much in grams of the mass of the ice is melted by the friction with the rough surface, assuming 75.0% of the internal energy generated stays in the ice. Latent heat of fusion [Lf) for water 333,700 J/kg. Provide your answer to three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your
