1.) A common belief is that a hole in a jet plane can suck a person out. On an episode of a popular TV series, the hosts attempted to determine whether this is possible. According to the hosts' experiment, such an event cannot happen.
Did they need to perform the experiment? As a science adviser to the show, the hosts ask you to perform a crude calculation to test the myth. A typical jet plane travels at 532 mph at a cruising altitude of 29500 ft. The windows on a jet plane measure 14.0 in × 14.0 in. Calculate the force exerted on such a window as the plane flies at 29500 ft above the sea level. Assume the density and pressure of air at 29500 ft are 0.470 kg/m3 and 308 mbar, respectively, but that the interior of the plane remains pressurized to atmospheric pressure, 1 atm.
2.)Calculate the fractional difference between this force and the weight wman of a typical adult male (185 lb).
