The definition of average velocity is.

Options

A. the average acceleration multiplied by the time.
B. distance travelled divided by the time
C. `(1)/(2)` (final velocity + initial velocity)
D. displacemnt divided by the time

Answer

D

Explanation

`v_(av) = ("Displacement")/("time")`
`v_(av) = (1)/(2) ("final velocity" + "initial velocity")` is valid only for constant acceleration.
