A Ferris wheel with a radius of 9.5 m rotates at a constant rate, completing one revolution every 32 s. Find the direction and magnitude of a passenger’s acceleration when (a) at the top and (b) at the bottom of the wheel. Suppose the Ferris wheel in the previous problem begins to decelerate at a rate of 0.22 rad/s2 when the passenger is at the top of the wheel. Find the direction and magnitude of the passenger’s acceleration at that time.

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.
