A block of ice at 0°C whose mass initially is m = 12.5 kg slides along a horizontal surface, starting at a speed vo = 4.10 m/s and finally coming to rest after traveling a distance d = 10.07 m. Compute the mass of ice melted as a result of the friction between the block and the surface. (Assume that all the heat generated owing to friction goes into the block of ice.)

i thought i had to use friction but it doesn't give me the coefficient of friction.

  • physics -

    work done: 1/2 m v^2

    compute that.

    Then, heat = work done= massice*Hf
