They are related as
- In a uniform circular motion, the magnitude of the speed does not change during the travel and only the instantaneous direction changes.
- This speed is always directed along the tangent to the circle at a given point. (refer to the figure attached)
- For any circular motion, the must-have acceleration is the centripetal acceleration that is directed towards the centre of the circular locus (if the motion has a tangential acceleration, it has a tangential acceleration additionally).
- Therefore, both the directions of the tangential speed and the centripetal acceleration are orthogonal to each other (perpendicular: one is 90 degrees apart from the other).
- In mathematics, 2 vectors (
,
) that are perpendicular to each other have a quality that their dot product (
) equal to zero vector (
) which is written as
.
- This quality can be considered when dealing with the velocity vector and the acceleration vector in a manner
.

1) In a circular motion, the angular displacement 
is given by
where S is the arc length and r is the radius. The problem says that the truck drove for 2600 m, so this corresponds to the total arc length covered by the tire:
. Using the information about the radius, 
, we find the total angular displacement:
2) If we put larger tires, with radius
, the angular displacement will be smaller. We can see this by using the same formula. In fact, this time we have:
where S is the arc length and r is the radius. The problem says that the truck drove for 2600 m, so this corresponds to the total arc length covered by the tire:
2) If we put larger tires, with radius
