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 … WebMay 9, 2024 · When you have uncertainty over a range of different values, taking the average (arithmetic mean) can serve as a reasonable estimate.
