## Homework Statement

To find the acceleration of a glider moving down a sloping air track, you measure its

velocities (v1 and v2) at two points and the time t it takes between them, as follows:

v1 = 0.210 +/- 0.05m/s

v2 = 0.850 +/- 0.05m/s

t = 8 +/- 1 second

What should you report for the acceleration, a = (v2 - v1)/ t and its uncertainty

## Homework Equations

a = (v2 * v1)/ t

## The Attempt at a Solution

Acceleration, a = (V2 – V1) / t = ((0.85 – 0.21) / 8.0) m/s =

__0.08 m/s2__

I need some clue on how to find the uncertainty in this question
