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.
What has to be the radius R, in order for the static friction to provide adequate Centripedal force? LOOK AT PICTURE
When the radius and the mass of the rotating object are held constant, does increasing the period increase or decrease the centripetal force? Explain how and why.
