The lockheed sr-71 blackbird may be the fastest non-research airplane ever built; it traveled at 2200 miles/hour (983 m/s) and was in operation from 1966 to 1990. its length is 32.74 m. (a) by what percentage would it appear to be length contracted while in flight? (b) how much younger would a pilot who took 1000 flights in the plane be compared to his twin on earth if each of his flights on the blackbird covered 3200km?

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
