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 2.9 kg rock is swung in a circular path
and in a vertical plane on a 4.7 m length
string. At the top of the path, the angular
velocity is 17 rad/s. What is the tension
in the string at that point?
