Question
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 512 mph at a cruising altitude of 25500 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 25500 ft above the sea level. Assume the density and pressure of air at 25500 ft are 0.562 kg/m3 and 382 mbar, respectively, but that the interior of the plane remains pressurized to atmospheric pressure, 1 atm.
?=
lb
Calculate the fractional difference between this force and the weight ?man of a typical adult male (185 lb).

- A very dense UFS (Unidentified Flying Sphere) has radius 1370_m and acceleration due to gravity 9.4 m/s at its surface. Find the mass of the sphere.

F.arrow_forwardRick is an Aerospace Engineer at NASA’s Jet Propulsions Laboratory (JPL), and is designing the next mission to Pluto called “New Horizons 2: The Sequel". This time Rick plans to study Pluto's largest moon Charon. Charon has a mass of 1.586 ×1021 kg and a mean radius of 606 km, and might have a nitrogenous atmosphere (N2) just like Pluto. If, for a massive object to have an atmosphere its escape speed must be 12 times greater than the root-mean- square (rms) velocity of the gas (otherwise the gas will slowly leak away over time), what is the maximum temperature that Charon can have and still have a nitrogenous atmosphere? [Charon has a temperature of -281 °C = 55 K, day or night.]arrow_forwardI've been moonwalking for hours, and I'm getting tired.

- You start out by driving 176 miles north in 2 hours and 26 minutes, and then you stop and park for a while. Finally you drive another 134 miles south in 3 hours and 38 minutes. The average velocity for your entire trip was 5.54 miles per hour to the north. How much time did you spend parked? 1 hours 30 minutes 3 hours 1 minutes 0 hours 45 minutes 7 hours 34 minutesarrow_forwardI keep getting this wrong despite working it out many times. Can I please get some insight on the right approach? A team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. With what minimum initial speed ?esc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? Assume that the asteroid is approximately spherical, with an average density ?=3.32×106 g/m3 and volume ?=2.40×1012 m3 . Recall that the universal gravitational constant is ?=6.67×10−11 N·m2/kg2 .
