Chapter 3, Problem 42P
Entrance and exit ramps for freeways are often circular stretches of road. As you go around one at a constant speed, you will experience a constant acceleration. Sup-pose you drive through an entrance ramp at a modest speed and your acceleration is 3.0 3.0 m/s2. What will be the acceleration if you double your speed?
