The object weighing 1 kg is thrown down from a height of 5 meters with a velocity of 10 m/s. The energy is not dissipated into the air through friction and not passed into the ground, but stays inside the object as an increase in the internal energy. You can approximate gravitational acceleration g=10 m/s2. When the object hits the ground and stop, its change of internal energy is:
