## Homework Statement

An ant clings to the outside edge of the tire of an exercise bicycle. When you start pedaling, the an't speed increases from ) to 10 m/s in 2.6 s. The wheel's rotational acceleration is 13 rad/s^s.

Determine the average tangential acceleration of the tire.

## Homework Equations

v=ω*r

a=∝*r

v=Δx/Δt

a=Δv/Δt

ω=ΔΘ/Δt

∝=Δω/Δt

## The Attempt at a Solution

I tried to manipulate the formulas that involved ∝, v and t in order to solve for a, but I couldn't get the radius to cancel out, or I kept ending up with ω in the equation. I need help figuring out how to convert rotational acceleration (∝) to linear acceleration (a) WITHOUT the radius.
