Question

an aeroplane flying at a height of 20000 M at speed of 300 km per hour has which type of energy?

Answer 1

the aeroplane have both energy kinetic energy as well as potential energy
the aeroplane have mechanical energy

Answer 2

The aeroplane has both kinetic and potential energy.

Let's see an detailed explaination:

• Kinetic energy is a type of mechanical energy possessed by an object by the virtue of its movement.

• Potential energy is a type of mechanical energy possessed by an object by the virtue of its position with respect to the reference frame.

$\boxed{KE = \dfrac{1}{2}m {v}^{2} \:\:and\:\:PE = mgh}$

Now the reference frame in this case is the earth surface.

So, both KE and PE has non-zero values as the plane is moving and is at a particular height from the earth surface.
