FREE Expert Solution

This problem deals with the relationship between angular acceleration, radial/centripetal acceleration, and tangential acceleration.

We'll also need to apply rotational kinematics because radial/centripetal acceleration depends on angular velocity.

Tangential acceleration:

at=rα

Centripetal/radial acceleration:

ac=v2r=rω2
