Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

A stuntman whose mass is 70 kg swings from the end of a
4.0-m-long rope along the arc of a vertical circle. Assuming he
starts from rest when the rope is horizontal, find the tensions
in the rope that are required to make him follow his circular
path (a) at the beginning of his motion, (b) at a height of
1.5 m above the bottom of the circular arc, and (c) at the bottom
of the arc.
