A bolt falls off of the landing gear of an airplane as it taking off from Tampa International Airport. At the instant, the bolt detaches from the plane, the plane's altitude is 667.0 meters and its velocity is 87.4 m/s at the angle of 60* with respect to the horizontal. What is the bolt's speed when it hits the ground?

Solutions

Expert Solution

Initial speed of the bolt is

Initial height of the bolt is

Let m be the mass of the bolt, the initial kinetic energy of the bolt is

Initial potential energy of the bolt is

Let vf be the speed of the bolt when it reach the ground. Final height of the bolt is hf=0. Final kinetic energy of the bolt is

Final potential energy of the bolt is

Assuming that there is negligible loss of mechanical energy of the bolt.

As an airplane is taking off at an airport its position is closely monitored by radar. The following three positions are measured with their corresponding times: x1 = 264.08 m at t1 = 4.90 s, x2 = 312.33 m at t2 = 5.40 s, x3 = 364.72 m at t3 = 5.90 s. What is the acceleration of the airplane at t2 = 5.40 s? (Assume that the acceleration of the airplane is constant.)​ a=_______m/s^2

After lowering the landing gear, the pilot notices that the "gear down and locked" light is not illuminated. "It's probably just a burned out light bulb," she says, as she proceeds on final approach for landing. Considering the pilot's hypothesis, which is the result of Type I error? Explain your choice! A. The sound of metal scraping on concrete will be heard upon landing. B. The landing is delayed unnecessarily while the bulb and gear are checked. C. We cannot...

“Main landing gear of each aircraft is used to absorb the load of the aircraft in landing/ take-off and also weight of it while it is on ground. After reaching its flight cycle, it needs to overhaul to keep aircraft safe. Write an essay how to inspect, clean and lubricate the bearing of main landing gear during maintenance. Make sure the procedure is complete.”

A “conventional gear” tailwheel airplane has the center of mass aft of the two main wheels and a smaller, third wheel at the tail. A “tricycle gear” airplane has the center of mass forward of the two main wheels and the third wheel near the nose. Consider a shiny, new airplane landing on its main wheels, with the fuselage at a left yaw angle with respect to the direction of motion down the runway. With which of these two types...
