A small ball is attached to the lower end of a 0.800-mm-long string, and the other end of the string is tied to a horizontal rod. The string makes a constant angle of 37.4 ∘∘ with the vertical as the ball moves at a constant speed in a horizontal circle. 1. If it takes the ball 1.60 ss to complete one revolution, what is the magnitude of the radial acceleration of the ball? Express your answer with the appropriate units. 2.

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.
