Unformatted text preview: you can state this result as 1.37±0.15 m). Now calculate the number of strides it takes to walk the trail from start to finish and estimate the uncertainty on this number. Be careful with units and significant figures. 2. The mass of a particular sample of rock retrieved from Mars is m = 772.2 ± 0.2 g. The sample is in the shape of a cylinder of height h = 10 ± 0.1 cm and base radius r = 2.5 ± 0.1 cm. Calculate the density of the rock sample in units of kg m3 . You must state your result in the correct units with its associated uncertainty. The volume of a cylinder is V = π r 2 h....
