Question

I need to find the centripetal acceleration of my clothes dryer. How would I go about doing it... Would the tangential speed just be 2pi*R*number of rotations/time, or how would I find that?

Put a shoe in the dryer. Count the number of times the shoe tumbles in a minute (that gives you rev/min) To get angular speed, muliply that by 2PI/60, so you have it in radians per second.

Now

multipy by r to get velocity.
