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 1.6 kg rock is swung in a circular path and in a vertical plane on a 2.9 m length
string. At the top of the path, the angular velocity is 18 rad/s. What is the tension in
the string at that point?
