Question:
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: 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 α = v2 – v1 t, what should you report for α and its uncertainty?
b. You calculate using an air resistance model that the acceleration should be 0.13 ± 0.01 m/s 2 . Does your measurement agree with this prediction?
