A block of ice of mass 50 kg is sliding on a horizontal plane. It starts with speed 5 m/s and stops after moving through some distance. The mass of ice that has melted due to friction between the block and the surface is: [Assuming that no energy is lost and latent heat of fusion of ice is 80 cal/g , J = 4.2 J/cal ] A. 2.86 g B. 3.86 g C. 0.86 g D. 1.86 g
