Homework Statement
A bicycle wheel has a radius of 0.5 m. When it spins, it completes one full turn in 1.6 s. Two identical rocks are stuck on the wheel at a radius of 0.4 m and 0.2 m. What is the ratio of the force on the outer rock to that of the inner rock?
Homework Equations
F=ma
F=mw^2r
F= (mv^2)/r
These are the only formula's I believe could be relevant
The Attempt at a Solution
I've looked at both f=(mv^2)/r and f=mw^2r but I just can't get it. I don't understand how I'm supposed to find the force with on the time and the radius. This led me to believe that I don't have to necessarily solve it but after that I'm lost
