Idont understand physics at all!

a small two passenger airplane taxing to the runway at 4 m/s has a takeoff speed of almost 30 m/s or more than 65 mi/hr. determine the minimum length of the runway for the plane to reach that speed if it only takes 15 seconds to reach that speed. show your work.

255

Explanation:

Let be the distance of runway.

Let be the initial velocity of aeroplane.

Let be the initial velocity of aeroplane.

Let be the time taken by Susan.

Given,

From the given information we can assume that no additional forces are acting.So,the acceleration is constant.

The length of runway will be minimum if the aeroplane takes off in seconds.

As we know from the equations of motion,

So,

So,the minimum length of the runway required is

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.

The answer is  a.first and third quarters
