Our goal is to use this video to measure the acceleration of the space shuttle Atlantis as it moves the first 74 meters after liftoff. The video is shown in 24 frames per second.
What is the last frame before the shuttle begins to move? (Do not enter units for this answer). = Answer is (147)
At what frame has the shuttle traveled 74 meters? (Do not enter units for this answer). = Answer is (263)
What is the elapsed time? = answer is (4.83 s)
Assuming constant acceleration, at what rate is the shuttle accelerating?
If the shuttle continued to move with this acceleration, what speed would it reach 37 s after launch?
If the shuttle traveled directly upwards, what would its altitude be at 37 s?
