Question

You're in an airplane that flies horizontally with speed 1100 km/h (300 m/s ) when an engine falls off. Neglecting air resistance, assume it takes 26 s for the engine to hit the ground.Find the height of airplane.

Answer 1

Answer:

The height of the airplane is 3312.4 meters.

Explanation:

Given that,

Speed of the airplane, v = 1100 km/h = 300 m/s

It takes 26 s for the engine to hit the ground. We need to find the height of the airplane. Using second equation of motion to find it as :

$h=ut+\dfrac{1}{2}at^2$

Here, u = 0 and a = g

$h=\dfrac{1}{2}gt^2\\\\h=\dfrac{1}{2}\times 9.8\times (26)^2\\\\h=3312.4\ m$

The height of the airplane is 3312.4 meters.
