The airplane would start off slow and then reach a faster speed at takeoff which leads me to believe that the average velocity would be slower than its speed at takeoff, but I'm not sure how to go about calculating that and that doesn't correspond to anything I have calculated.
Homework Statement
Starting from rest an airplane lifts off the ground after 40s and 1.8km. What is its speed at takeoff and its average acceleration during the takeoff run?
Homework Equations
V= distance/time
Acceleration= (Vf-Vi)/time
The Attempt at a Solution
The airplane travels 1.8km in...
