1. The problem statement, all variables and given/known data You are standing on a merry-go round spinning at 12 rpm. The radius of the merry-go round is 5 meters, and you have a mass of 57kg. What static frictional force between your shoes and the merry-go round is required to keep you from flying off? 2. Relevant equations Vc=(2*pi*r)/T Ac=(Vc^2)/R Fnet=MA 3. The attempt at a solution Alright here goes... Vc=(2*pi*r)/T so Vc=(2*pi*5)/.2 = 157 Ac=(157^2)/5 =4934 here is where I get confused... I think I should use Fnet=ma so it would be Fnet=(57)(4934) I'm not sure what Fnet is composed of though...where does the coefficient of friction come in?
