[SOLVED] Instantaneous velocity and Average velocity
An airplane maintains a constant acceleration of 4.0m/s^2 [E] as it speeds up from 16m/s [E] to 28m/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?
This is the question I need help on. I know a time is required for this question, though is the instantaneous velocity required too? If it is, how would I solve for it?
