An experimenter is trying to determine the average speed of an object falling to the ground from a height of 2 m, starting from rest. To determine the height, a meter-stick is used (uncertainty: ± 2 cm). To determine the time, a camera is used. The camera records 20 frames per second, so its uncertainty is 0.05 s. The experimenter finds that it took 0.63 seconds for the object to fall. Determine the minimum and maximum values for time, distance and average speed. Show your calculations below, and enter your results in the provided table.
