How do you find the Magnitude of tangential acceleration if you have uniform circular motion? I know the formula for Tangential Acceleration; however I have no clue how to apply it to determine the Magnitude?

No, I mean tangential acceleration. That's probably the answer I'm looking for I just have to know how to express that the acceleration would be zero if it was uniform circular motion using words and one equation.

Im suppose to use At=[dv/dt].

Tangental acceleration can still exist on a object traveling in a circular path. The centripetal force just needs to change with respect to speed^{2}, so it always equals m v^{2} / r.
The magnitude of tangental acceleration would be the magnitude of angular acceleration times r = angular acceleration x r.
