Find the potential energy of a pigeon weighing 200 g flying 8 m above the ground at a speed of 85 km / h.

The potential energy of a dove in the gravitational field of the Earth is calculated by the formula:
Ep = mgh, where m is the mass of the pigeon (m = 200 g = 0.2 kg), g is the acceleration of gravity (we take g = 10 m / s ^ 2), h is the height of the pigeon relative to the earth’s surface (h = 8 m ).
Let’s calculate the potential energy of the pigeon:
Ep = mgh = 0.2 * 10 * 8 = 16 J.
Answer: The potential energy of a pigeon is 16 J.
