## Homework Equations

## The Attempt at a Solution

I feel like that should be a really simple question if I had formula. We were given that:

ωwheel=(R1/R2)ωpedal

R1 is the radius of the crank sprocket

R2 is the radius of the wheel sprocket

This would mean that ωwheel=(2/5)ωpedal, but that doesn't really help.
