In the cliff jump photograph, I can estimate the frames per second shot by the camera based on a few assumptions:
- The man is of average height, 1.77 meters.
- There is no significant vertical component to the initial velocity of the jump.
- The first frame is taken at precisely the moment of the jump.
Then we estimate the total height of the jump by measuring (using Photoshop) the vertical distance in pixels from the top of the man's head in the first frame to the corresponding point in the last frame just prior to the splash, and divide this by the height of the man in pixels. This gives me roughly a ratio of 5.04, and under assumption 1, this means the vertical distance of the jump to the water is about D = 8.9 meters.
Using the formula D = (1/2) g t^2, where D is displacement, g = 9.8 m/s^2 is the acceleration due to gravity, and t is time, we find that the jump took a total time of approximately 1.35 seconds. This is probably a bit longer than the actual time, which I think should be closer to 1 second.
There are about 12 frames that were shot in the composite. This gives a frame rate of 12/1.35 = 8.89 frames per second for the camera that shot these images.
More interestingly, given the frame rate of the camera, I can estimate the approximate height of the jump, and therefore, the height of the man. I could even give error bounds for these heights.
