Suppose a wheel with a tire mounted on it is rotating at the constant rate of

2.27

times a second. A tack is stuck in the tire at a distance of

0.393

m

from the rotation axis. Noting that for every rotation the tack travels one circumference, find the tack's tangential speed.

tangential speed:

What is the tack's centripetal acceleration?

centripetal acceleration:
