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

3. A 0.35 kg ball is spinning in a uniform horizontal circle on the end of a 0.52 m string with a speed of
1.5 m/s. What is the radial (centripetal) acceleration of the ball? How much force is required to
keep the ball spinning at this speed?
