At the equator, the radius of the Earth is approximately 6370km. A jet flies at a very low altitude at a constant speed of v=237m/s. Upon landing, the jet can produce an average deceleration of magnitude a=21.5m/s^2. A. How long, in seconds, will it take the jet to circle the Earth at the equator?  B. What is the minimum landing distance, in meters, this jet needs to come to rest? Assume that, when the jet initially touches the ground, it is moving at the same speed as it was when it was flying.

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.
