a 3 kg model rocket is launched vertically and reaches
andaltitude of 60 m wih a speed of 28 m/s at the end of flight,
timet=0. as the rocket approaches its maximum altitude itexplodes
into two parts of masses ma = 1 kg and mb = 2 kg. part a is
observed to strike the ground 74.4 m west of the launchpoint at t =
5.85 s. determine the position of part b at thattime.

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.
