A 2.5 kg block of ice at a temperature of 0C and an initial speed of 5.7 m/s slides across a level floor. If 3.3*10^5 J are required to melt 1.0 kg of ice, how much ice melts, assuming that the initial kinetic energy of the ice block id entirely converted to the ice's internal energy?

  • Physics - ,

    initial KE= heat released
    1/2 2.5*5.7^2=heat released.

    heat released=massicemelted*3.3E5J/kg

    solve for massicemelted
