You are riding a dirt bike around a vertical loop that is in a spherical cage.  In order for the dirt bike to maintain good traction, you want the normal force of the loop on the dirt bike to be at least twice the weight of the dirt bike when you are at the bottom of the cage.  If the sphyrical cage has a radius of 7m, what is your speed at the bottom of the sphyrical cage?  Construct the free body diagram of the dirt bike when it is at the top of the loop.

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.
