A common belief is that a hole in a jet plane can suck a person out. On an episode of the popular TV series Myth Busters, hosts Adam and Jaime attempted to find whether this is possible. According to the hosts experiment, such an event cannot happen (that is, they busted the myth). But did they need to perform the experiment? As a science advisor to the show, Adam and Jaime ask you to perform a crude calculation to test the myth. A typical jet plane travels at 552 miles per hour at a cruising altitude of 28500 feet. The windows on a jet plane measure 14.0 in × 14.0 in. Obtain the force exerted on such a window as the plane flies at 28500 feet. above the sea level. (Suppose the density and pressure of air at 28500 ft is 0.492 kg/m3 and 324 mbar but the interior of the plane remains pressurized to atmospheric pressure, that is, 1 atm.)
