Motion pictures typically are filmed and shown at a speed of 24 frames per second, where a frame is a single photographic image in the film. A motion- picture camera that moves the film at 2.4 x 10^5 frames per second is used in high-speed photography. When the film is shown again at 24 frames per second, the filmed object seems to move very slowly. This technique is used to analyze the motion of objects, like bullets, that move too quickly to be observed by the human eye. If a frame of 16-mm film is 0.75 cm in length, how fast does the film move through the high-speed camera when the film is being exposed?
