To find the acceleration of a glider moving down a sloping air track, you measure its velocity at two points (v1 and v2); and the time t it takes between them: 3. v1 = 0.21 ± 0.05 m/s v2 = 0.85 + 0.05 m/2 t = 8.0 ± 0.1 s a. Assuming all uncertainties are independent and random, and acceleration is calculated using a = vz – Vi what should you report for a and its uncertainty?
