Circluar Motion Involving Rotations Per Minute
1. The problem statement, all variables and given/known data
What is the magnitude of the acceleration of a speck of clay on the edge of a potter's wheel turning at 40 rpm (revolutions per minute) if the wheel's diameter is 35 cm?
2. Relevant equations
3. The attempt at a solution
2(3.14)(.175)/.67 = 1.099

Welcome to PF.
Isn't your period 1.5 instead of .67?
You only get 40 revs per min so a rev should be longer than a sec no?
