1. The problem statement, all variables and given/known data If the radius of a merry-go-round is 11 meters, and it takes 15 seconds to go around once, what is the speed of an atom at the outer rim? 2. Relevant equations C = 2 [tex]\pi[/tex] r v = m / s 3. The attempt at a solution C = 3.14 * 22 (gives distance traveled, 1 trip) Multiply by 2 (i.e. 2 trips as indicated by problem) divide by the time, 15s Answer was told to be wrong, I thought it rather simple, did I make a calculation error somewhere?
