Answer:

The required velocity of the plane when it just leaves the ground is 100 m/s.

Explanation:

In the above Question, the following information is given -

The length of the runway is 500 m.

The aeroplane leaves the ground 10 seconds

after the start.

The speed of the aeroplane while on the ground

>> (500 m / 10 s) = 50 m/s.

Now, Let us find the acceleration of the plane.

According to the Second Equation Of Motion

S = ut+ (1/2) at²

The plane is innitially at rest.

So, u = 0

500=(1/2) × a × 100

=> Acceleration = 10 m/s.

Now according to the First Equation Of Motion

v=u+at

=> v= 0 + 100

=>v=100 m/s.

So, the required velocity of the plane when it just leaves the ground is 100 m/s.
