A10- m -long glider with a mass of 680 kg (including the passengers) is gliding horizontally through the air at 20 m/s when a 60 kg skydiver drops out by releasing his grip on the glider. part a what is the glider's speed just after the skydiver lets go?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
