Glad I could help out!

In problem 25 of the presentation on Rotational Kinematics the radius used is the diameter of the wheel. Could you explain why.

Ann Marie - it's an error! To keep the answers the same, I'm just going to change diameter to radius in the question. A new presentation will be done in a couple of days - I have to re record the slides. Thank you for spotting this, John.

I realized my error. No need to answer.
