Air enters an adiabatic nozzle steadily at 300 kpa, 200 ℃, and 45 m/s and leaves at 100 kpa and 180 m/s. the inlet area of the nozzle is 110 cm2. determine (a) the mass flow rate through the nozzle, (b) the exit temperature of the air, and (c) the exit area of the nozzle.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
