A small aeroplane that can accelerate at 5.5 m s-2, when its engines are on full power, must reach a speed of at least 198 km h-1 before it can takeoff.
(a) Can the plane takeoff on a 300 m long runway?
(b) Calculate the minimum length of the runway and the minimum time required for takeoff.
(c) Calculate the minimum length of the runway and the time required for takeoff, if the plane starts by accelerating at 2.75 m s-2 for 4.0 s before the engines are put to full power, when the acceleration changes to 5.5 m s-2.
