a jetliner traveling northward is landing with a speed of 80 m/s. Once the jet touches down, it has 800 m of runway in which to reduce its speed to 10 m/s. (a) Compute the average acceleration (magnitude and direction) of the plane during landing (take the direction of the ...

A lump of ice falls from a jet plane as it tries to land at an airport. If the ice hits the ground with a vertical speed of 85m/s, what was the height of the plane when the ice fell off.

While taking a plane flight to a meeting, a physicist decides to do a mental calculation of how much fuel the plane would consume in the absence of friction, assuming its engines have an efficiency of 22.0% and the mass of the plane is 200,000 kg. Each gallon of jet fuel ...
