## Homework Statement

The descending mass of the pulley system (atwood machine) is 60g and the ascending mass is 55g. Using DataStudio to measured the slope of the velocity over time (read by the spinning spokes of the pulley) the acceleration (constant) is experimentally given as 0.316m/s^2. Now they want to know the theoretical acceleration so you can find the % error.

## Homework Equations

They ask you to solve for (m2-m1)g in the same data table in the lab book. (m2-m1)g = (65-55)9.8 = 49N

## The Attempt at a Solution

I used f=ma and other equations and I keep on getting 9.8m/s^2 as the acceleration. This makes sense to me because the objects are acted on by gravity, but the main confusion is: WHY IS THE ACCELERATION MEASURED AS 0.316m/s^2 and not 9.8m/s^2?
