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 determine 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 508 mph at a cruising altitude of 27500 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 27500 ft. above the sea level. (Assume the density and pressure of air at 27500 feet is 0.512 kg/m3 and 348 mbar but the interior of the plane remains pressurized to atmospheric pressure, that is, 1 atm.) Calculate the fractional difference between this force and the weight wman of a typical adult male (185 lb).
Determine the period of the wave motion.
If a 37.2N horizontal force must be applied to slide a 15.8kg box along the floor at constant velocity what is the coefficient of sliding friction between the two surfaces.
A positive charge of 0.800? C is located in a uniform field of 1.20×105 N/C. A negative charge of -0.400? C is brought near enough to the positive charge that the attractive force between the charges just equals the force on the positive charge du..
Two automobiles, each of mass 900 kg, are moving at the same speed, 15 m/s, when they have an inelastic collision.(a) In what direction and at what velocity does the wreckage move if one car was driving north and one south? (b) In what direction a..
At full power, how long would it take for car to accelerate from 0 to 56 mph? Neglect friction and air resistance.
A person is making homemade ice cream. She exerts a force of magnitude 22 N on the free end of the crank handle, and this end moves in a circular path of radius 0.28 m. The force is always applied parallel to the motion of the handle. If the handl..
