The green light behind you is 0.25 miles away. You were stopped by a police officer exactly ten seconds after passing it. If the speed limit is 60m/hr, can you get out of this ticket, or will you have to pay the fine? Plz help

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)
