Please answer this Physics question.

Question 7 (1 point} A(9.80x10"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 [Lfi for water 333,700 JKkg. Provide your answer to three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. [3 x10 Your
