An airplane maintains a constant acceleration of 4.0m/s^2 as it speeds up from 16m/s [E] to 28 m/s [E].
A what is the average velocity?
b) how long does the airplane accelerate?
c) when is the instantaneous velocity equal to the average velocity for the interval?
a= 4.0 m/s^2
vi= 16m/s [E]
The Attempt at a Solution
i found the answer to A and B
Average velocity = 22 m/s. Total time = 3.0 s
I don't know how instantaneous velocity is related to average velocity for the interval. Or how to find the answer. Someone help me?
