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?
