Question

An aircraft has a take-off speed 180km/h and has length 250m from the start just before take-off a serious snag is detected in the engine and the aircraft failed to take-off. There is a wall at a distance of 270 m from takeoff point

Answer 1

d = 270m = Required stopping distance.

Vo = 180km/h = 180,000m/3600s = 50m/s. = Initial velocity before take-off.

V^2 = Vo^2 + 2a*d.
0 = (50)^2 + 2a*270
-540a = 2500
a = -4.63m/s^2.

V = Vo + a*t.
0 = 50 - 4.63t
t = ?.
