A circular object with a diameter of 5cm is rolling on a horizontal surface moving at 2m/s. It then rolls down an incline with a 30° angle below the horizontal, as it rolls down it takes 5.25 s at an constant acceleration of 1.2rad/s before setting on a second horizontal surface. What is the vertical height that the object travelled?

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.
