An aircraft has a liftoff speed of 30m/s. What minimum constant acceleration does this require if the aircraft is to be airborne after a takeoff run of 240 m ?

a = 1.875 [m/s²]

Explanation:

The plane begins to move from rest to reach the take-off speed, by means of the following equation of kinematics we can calculate the acceleration.

where:

vf = final velocity = 30 [m/s]

vo = initial velocity = 0

a = acceleration [m/s²]

x = distance = 240 [m]

double the distance = divide strength by 4
