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 coin placed 30.0cm from the center of a rotating, horizontal turntable slips when its speed is 50.0cm/s

(a) What force causes the centripetal acceleration when the coin is stationary relative to the turnable?

(b) What is the coefficient of static friction between coin and turntable?
