An aircraft has a liftoff speed of 33 m/s. What is the minimum constant acceleration an

airplane must have to reach that takeoff speed if the runway is only 240 m long?

Answer: The minimum acceleration for the air plane is 2.269m/s2.

Explanation: To solve such problem the equation of motion are applicable.

The initial velocity is 0 since the airplane was initially standing. We are going to use this equation

V^2=U^2+2as

33^2=0+2a (240)

a = 2.269m/s2
