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.

Braving the Rotor at the Amusement Park (Circular Motion Due to Normal Force) The Rotor is an amusement park ride where people stand against the inside of a spinning cylinder, as shown below. Once the cylinder is spinning at a certain speed, the floor drops out of the bottom of the cylinder but the people do not fall out of the bottom. A conservative low estimate of the coefficient of static friction between people's clothes and the cylinder wall is 0.45. The radius of the cylinder is 2.4 m. What is the minimum number of rpm that the cylinder can have so that the people do not fall out the bottom? (answer: 29 rpm)
