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.

In one amusement park ride, riders enter a large vertical barrel and stand against the wall on its horizontal floor. The barrel is spun up and the floor drops away. Riders feel as if they are pinned to the wall by a force something like the gravitational force. This is an inertial force sensed and used by the riders to explain events in the rotating frame of reference of the barrel. Explain in an inertial frame of reference (Earth is nearly one) what pins the riders to the wall, and identify all forces acting on them.

On the ride "Spindletop" at the amusement park Six Flags Over Texas, people stood against the inner wall of a hollow cylinder with radius 2.9 m and axis vertical. The cylinder started to rotate, and when it reached a constant rotation rate of 0.59 rev/s, the floor on which the people were standing dropped about 0.61 m. The people remained pinned against the wall. What minimum coefficient of static friction is required if a person on the ride is not to slide downward to the new position of the floor?
