Devin Longo

## Homework Statement

A cyclist starts from rest and pedals so that the wheels make 8.5 revolutions in the first 4.5 s. What is the angular acceleration of the wheels (assumed constant)?

## Homework Equations

$$\alpha$$ = $$\Delta$$$$\omega$$/ $$\Delta$$t

## The Attempt at a Solution

I converted 8.5 to radians and divided by 4.5. BUT I CANT GET THE RIGHT ANSWER!
