11.9. We will learn in Chapter 6 that the force F necessary to keep an object moving in a circle is directly proportional to the square of the object's speed, v². a. As v increases what happens to v² (does it increase or decrease)? What then happens to F (does it increase or decrease)? b. Write an equation that relates the two variables F, v² using an unknown constant k. c. A car moving around a circular track at a speed of 20 mile/hour requires the frictional force between its tires and the ground to be 500 pounds. What is the value and units of the proportionality constant. What is the equation that relates the two variables F, v² using an unknown constant k.
