Acar is up on a hydraulic lift at a garage. the wheels are free to rotate, and the drive wheels are rotating with a constant angular velocity. does a point on the rim of the wheel have: a. a tangential velocity? b. a tangential acceleration? c. a centripetal acceleration?

Explanation:

Given

Wheels are rotating with constant angular velocity let say

Presence of constant angular velocity show that there is no angular acceleration thus there is no tangential acceleration.

But any particle on the rim will experience a constant acceleration towards center called centripetal acceleration.

(a) yes, there will be tangential velocity which is given by

where r=radial distance from center

(b)tangential acceleration

there would be no tangential acceleration as velocity is constant

(c)centripetal acceleration

Yes, there will be centripetal acceleration given by
