A system of mass 10 kg undergoes a process during which there is
no work, the elevation decreases by 50 m, and the velocity
increases from 15 m/s to 50 m/s. The specific internal energy
decreases by 5 kJ/kg and the acceleration of gravity is constant at
9.8 m/s2. Determine the change in kinetic energy, in kJ,
and the amount of energy transfer by heat for the process, in
kJ.
