closed system having a mass of 50 kg has an initial velocity of 10 m s Subsequently its velocity increases to 30 m s and its elevation also rises by 40 m During this process the system receives 30000 J of heat and 4500 J of work If the system delivers 0 002 kWh of electrical energy make calculations for a change in the internal energy of the system
