(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A tire 0.319 m in radius rotates at a constant

rate of 98.4 rev/min.

Find the speed (relative to the tire’s axle)

of a small stone lodged in the tread on the

outer edge of the tire.

Answer in units of m/s.

Find the acceleration of the stone.

Answer in units of m/s2.

2. Relevant equations

V=2*pi*r*f

a_{c}= v^{2}/r

3. The attempt at a solution

I basically solved for the velocity of the tire which is 197.22 m/s

how do you find the relative speed ?? If you could find the velocity I would be able to solve for the acceleration. Thank you
