An aircraft has a liftoff speed of 53 m/a what is the minimum constant acceleration an airplane must have to reach that takeoff speed if the runway is only 420 m long

Explanation:

Constant Acceleration

It refers to those cases where the change of the velocity is the same over time, i.e. the velocity changes same quantities in same times. If we set initial speed, final speed, a= acceleration, x= distance, then, the scalar equation between them is

The aircraft needs to reach a liftoff speed of 53 m/s assumed it starts from rest and has only 420 meters to reach that speed. Let's compute the acceleration by solving the above equation for a, with , , x=420:
