Two pictures are taken of a moving car 3 seconds apart, each with the shutter open for 1ms. The car traverses 8 mm during the first exposure, and 20 mm during the second.
(a) Find the average acceleration during the 3-s-interval, and the distance traversed if the acceleration was constant.
(b) Instead, if it is known only that the car never decelerated-that its velocity never decreased during the interval, what is the minimum and what is the maximum mathematically possible distance, consistent with the same given information? I;;lustrate with graphs of velocity vs time.
