If the velocity of a body changes from 13 m/s to 30 m/s while undergoing constant acceleration, what's the average velocity of the body

a-17 m/s
b-19.5 m/s
c-28 m/s
d-21.5 m/s

If the velocity of a body changes from 13 m/s to 30 m/s while undergoing constant acceleration, the average velocity of the body is 21.5 m/s. the answer is letter D. Velocity is a vector quantity and average velocity can be defined as the sum of the initial and final velocity divided by 2 at constant acceleration.

true tan speed = ang vel x radius
