To find the acceleration of a glider moving down a sloping air track, you measure its velocity at two points (?1 and ?2); and the time t it takes between them: v1 = .21 ± 0.05 m/s v2 = .85 ± 0.05 m/s 2 = 0 t = 8.0 ± 0.1 s a. Assuming all uncertainties are independent and random, and acceleration is calculated using a = (v2-v1)/t, what should you report for a and its uncertainty? b. You calculate...

After calibrating a test anemometer against a standard in a wind tunnel, you obtain the following mathematical function that relates the test anemometer wind speed values, Va, to the "true" standard wind speed, Vs: เสี Vs AVaB, where A 1.02 0.03 and B 0.3t 0.1 ms1. By examining the standard deviation of Va at several different wind speeds you also estimate any individual Va value has an uncertainty of 0.3 ms 1. The mean measured wind speed, Vawas 3 m/s....
