When a car crashes, its velocity changes from, say 60 mph to 0 mph in a short amount of time. the driver of the car also has the same change in velocity (assuming the driver is strapped in). when an airbag deploys in a crash, the car and driver have the same change in velocity.
how do airbags protect the driver in a crash, then?

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
