3.)Two students are asked to find the height of a particular building using a barometer. Instead of using the barometer as an altitude-measuring device , they take it to the roof of the bulding and drop it off, timing its fall. One student reports a fall time of 2.0 sec., and the other, 2.3 sec.. How much difference does the 0.3 sec make for the estimates of the building's height.
