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.

Question

If you have ever been on Woodsprings Road coming into Jonesboro, you have probably gone over the overpass and make a sharp curve to reach Alexander Drive. If I am driving my 1,176 kg car with a speed of 14 mi/h, and the radius of that curve is 44 feet, what is my centripetal force going around the curve in kiloNewtons, kN? Round to 2 decimal places.

Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
