The “Vomit Comet.” In Zero-gravity astronaut training equipment testing, NASA flies a KC135A aircraft along a parabolic flight path. As shown in Figure P4.47, the air-craf climbs from 24000ft to 31000ft,where it enters a parabolic path with a velocity of 143m/s at 45 degrees nose low. during this portion of the flight, the aircarft and objects inside its padded cabin are in free fall;astronauts and equipment float frely as if there were no gravity.what are the aircraft's (a)speed and (b) altitude at the top of the maneuver? (c) what is the time interval spent in microgravity?
