4the aviation department at the old coleman avenue facility had a small supersonic wind tunnel with a test section 1 inch in height. the operating conditions were such that the reservoir pressure and temperature were 1,2000r and 8 atmospheres. the exit temperature of the tunnel was 9500r. the mass flow rate through the tunnel was 0.5 slug/s. using the energy equation and isentropic relations, determine the reservoir density, exit velocity, exit density, exit pressure and exit area. for air, cp = 6,000 ft lb/slug 0r. assume standard sea level conditions.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
