Calculate the Tension of a Cord for an Object Spinning in a Circle

Follow us:

A 2 kg ball is whirled in a vertical circle via a cord of radius 1 m at a constant velocity of 6.28 m/s. Calculate:

(a) the tension in the cord at the top of the motion,
(b) the tension in the cord at the bottom of the motion, and
(c) the minimum velocity to keep the mass from “falling out” at the top of the circle.
