Answer:
Average velocity of the body is 21.5 m/s
Explanation:
It is given that,
The velocity of a body changes from 13 m/s to 30 m/s while undergoing constant acceleration.
The initial velocity of the body, u = 13 m/s
The final velocity of the body, v = 30 m/s
It is moving under constant acceleration. The sum of initial velocity and final velocity divided by 2 is called the average velocity of the body. It is given by :
[tex]v_{avg}=\dfrac{u+v}{2}[/tex]
[tex]v_{avg}=\dfrac{13\ m/s+30\ m/s}{2}[/tex]
[tex]v_{avg}=21.5\ m/s[/tex]
Hence, the average velocity of the body is 21.5 m/s
