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?

Lately, Jason has been taking drivers' ed so that he can get his license. However, he's
also been taking physics, and so he wonders what his acceleration is, when he drives
on a circular path in an empty parking lot near Peachtree Mall with diameter 78.0 m,
if he is driving at a constant speed of 23.0 m/s.
What is his acceleration?
O
66.1 m/s²
13.6 m/s2
O

- You are driving your car along a country road at a speed of 27.0 m/s. As you come over the crest of a hill, you notice a farm tractor 25 m ahead of you on the road, moving in the same direction as you at a speed of 12.0 m/s. You immediately slam on your brakes and slow down with a constant acceleration of magnitude 8 m/s2. Will you hit the tractor before you stop? Ο NO O Yes How far will you travel before you stop or collide with the tractor? 6.5 X m If you stop, how far is the tractor in front of you when you finally stop?
