An eagle that has a mass of 4.5 kg is spotted 5 m above a lake. it flies up to its nest in a tree at a height of 25 m. how much gravitational potential energy did the eagle gain?

900 J

Explanation:

Given, mass of eagle, m=4.5 kg

Initial height ,

Final height ,

Gain in height=

We know Gravitational potential energy of an object is given as

Here , g is acceleration due to gravity=9.8

          M is mass of object.

           h is height of object.

Now, gain in potential energy =

Therefore , this is the required solution.
