A car travels at 80 km/h on a level road in the positive direction of an x axis. Each tire has a diameter of 66 cm. Relative to a woman riding in the car and in unit-vector notation, what are the velocity v at the
(a) Center,
(b) Top, and
(c) Bottom of the tire and the magnitude a of the acceleration at the
(d) Center,
(e) Top, and
(f) Bottom of each tire? Relative to a hitchhiker sitting next to the road and in unit-vector notation, what are the velocity v at the
(g) Center,
(h) Top, and
(i) Bottom of the tire and the magnitude a of the acceleration at the
(j) Center,
(k) Top, and
(l) Bottom of each tire?
