If Julie is wearing her seat belt, she comes to rest in a time of 0.20 seconds. What is the magnitude of the average force (in newtons) exerted on Julie (mostly by the seat belt) as she is slowing down

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)
