GATE Mechanical Engineering (ME) 2015 Shift 2 Solved Paper

Work is done on an adiabatic system due to which its velocity changes from 10 m/s to 20 m/s, elevation increases by 20 m and temperature increases by 1 K. The mass of the system is 10 kg C_v = 100J/(kgK) and gravitational acceleration is 10 m/s². If there is no change in any other component of the energy of the system, the magnitude of total work done (in kJ) on the system is________
