Exercise 3: Plotting Rotational Acceleration

3. Use the ω(t) data to calculate (as best you can), the angular acceleration, α, of the IOLab over the time interval.

a) What are the units of α(t)? Plot α(t) on the same graph as ω(t). (This is not technically correct since they don’t have the same units, but it will make them easier to compare.)

b) What is the direction of α(t) during the rotation?
