as a person pushes a box across the floor the energy from the person‘s moving arm is transferred to the box in the box in the floor become warm during the process what happened to the energy

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

What object a collides with object b and bounces back its final momentum is?
