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 magni- tude 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?
