hey guys, i was wondering if anyone could explain how to find the linear acceleration of a point at the top and bottom of a wheel. the homework problem is as follows (just so you know the context, i don't want the answers, i want to know how to go about this.):
Consider a 61 cm diameter tire on a car traveling at 50 km/h on a level road in the positive direction of an x axis.
(a) Relative to a woman in the car, what is the linear velocity v of the center of the wheel.
m/s
(b) What is the magnitude a of the linear acceleration?
m/s2
(c) What is v for a point at the top of the tire?
m/s
(d) What is a for a point at the top of the tire?
m/s2
(e) What is v for a point at the bottom of the tire?
m/s
(f)What is a for a point at the bottom of the tire?
m/s2 Now repeat the questions relative to a hitchhiker sitting near the road.
(g) What is v at the wheel's center?
m/s
(h) What is a at the wheel's center?
m/s2
(i) What is v at the tire top?
m/s
(j) What is a at the tire top?
m/s2
(k) What is v at the tire bottom?
m/s
(l) What is a at the tire bottom?
m/s2
