Question

A light plane must reach a speed of 40m/s for takeoff.

Part A

How long a runway is needed if the (constant) acceleration is 2.8m/s2 ?

Answer 1

Answer #1

v^2 = v0^2 + 2 a x

40^2 = 0^2 + 2 *2.8*x

x = 40^2/(2*2.8)= 285.7 m

Answer 2

Answer #2

We know,

$v^{2}=u^{2}+2ad$

here u=0 as planes usually starts from rest for take off.

$40^{2}=0^{2}+2\times 2.8d$

d=285.71 m

To take off from the ground, an airplane must reach a sufficiently high speed. The velocity required for the takeoff, the takeoff velocity, depends on several factors, including the weight of the aircraft and the wind velocity. 1.) A plane accelerates from rest at a constant rate of 5.00m/s2 along a runway that is 1800m long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time tTO needed to take off?...

An Airbus A310 is initially moving down the runway at 7.0 m/s preparing for takeoff. The pilot pulls on the throttle so that the engines give the plane a constant acceleration of 1.8 m/s2. The plane then travels a distance of 1500 m down the runway before lifting off. How long does it take from the application of the acceleration until the plane lifts off, becoming airborne?

After touchdown a fighter jet passes a marker on the runway at an instantaneous speed of 100 m/s and constant negative acceleration of -15 m/s2. After slowing down to 25 m/s, the pilot suddenly goes to full power to provide a new constant acceleration of 34 m/s2 for a "touch and go" takeoff. How far from the original runway marker does the plane achieve its takeoff speed of 147 m/s?

After touchdown a fighter jet passes a marker on the runway at an instantaneous speed of 100 m/s and constant negative acceleration of -15 m/s2. After slowing down to 25 m/s, the pilot suddenly goes to full power to provide a new constant acceleration of 37 m/s2 for a "touch and go" takeoff. How far from the original runway marker does the plane achieve its takeoff speed of 160 m/s?
