Consider a 66-cm-diameter tire on a car traveling at 80 km/h on a level road in the positive direction of an x-axis.
Relative to a woman in the car, what are (a) the translational velocity v and (b) the magnitude a of the translational acceleration of the center of the wheel?
What are (c) v and (d) a for a point at the top of the tire?
What are (e) v and (f) a for a point at the bottom of the tire?
Now repeat the questions relative to a hitchhiker sitting near the road: What are (g) v at the wheel’s center, (h) a at the wheel’s center, (i) v at the tire top, (j) a at the tire top, (k) v at the tire bottom, and (l) a at the tire bottom?
What equations would you use to solve this, and can you show your work?
