2021 F = ma Exam — Question 9

NASA trains astronauts to experience weightlessness with an airplane which flies in a parabolic arc with constant acceleration g toward the ground. The plane can remain on this trajectory for at most 25 seconds, due to the large change in altitude required. If instead of simulating weightlessness, NASA wanted to fly a trajectory that would simulate the gravitational acceleration of Mars 3.7 m/s2 , for what length of time can the plane simulate Mars gravity? Assume that the maximum change in altitude is the same for both trajectories. — Source: Question 9, 2021 F = ma Exam, © 2021 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
