The 24-lb space-shuttle orbiter touches down at about 228 mi/hr. at 181 mi/hr its drag parachute deploys. at 36 mi/hr, the chute is jettisoned from the orbiter. if the deceleration in feet per second squared during the time that the chute is deployed is -0.00034v2 (speed v in feet per second), determine the corresponding distance s traveled by the orbiter. assume no braking from its wheel brakes.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
