The radius of the tires on a particular vehicle 0.62m if the tires are rotating 5 times per second, what is the velocity of the vehicle?

Circumference of the tire = (2 pi) x (radius)

= (2 pi) x (0.62 meter)

= 3.9 meters

If the tire never slips or skids, then the speed of the vehicle is

speed = (distance) / (time to cover the distance)

= (5 x 3.9 meters) / 1 second

= 19.48 meters/second.

(about 43.6 miles per hour).

We can't say anything about the vehicle's velocity, because we have

no information about the direction in which it's heading.
