Answer:
D
Step-by-step explanation:
Calculate v = (v + u) / 2. ...
Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two.
The average velocity calculator solves for the average velocity using the same method as finding the average of any two numbers. ...
Given v and u, calculate v. ...
Given v and v calculate u.
Answer is D
