WebTo find the uncertainty in 𝑑, we note that 𝑑 is defined as a product, so we use the product rule for combining the uncertainties of 𝑣 and 𝑡. From the statement, we see these are 𝜎 = 0. 1 / m s and 𝜎 = 0. 0 5 s. Therefore, the total percent uncertainty is 𝜎 𝑑 = 1 0 0 × 0. 5 2 0 + 0. 1 / 2 / = 7. 5 %. s s m s m s.
