Two stretched cables both experience the same stress. The first cable has a radius of 3.2x10-3 m, and is subject to a stretching force of 250 N. The radius of the second cable is 5.2x10-3 m. Determine the stretching force on the second cable.

Identify the forces that contribute to the centripetal force on the object in each of the following examples: a. a bicyclist moving around a flat, circular track b. a bicycle moving around a flat, circular track c. a racecar turning a corner on a steeply banked curve
