Question

A bird flies from the ground to a height of 200 m if the bird has a mass of 1.5 kg how much gravitational potential energy does it gain

A 500 j

B 1960 j

C 2940

D 300 j

Answer 1

Gravitational potential energy is equal to (mgh) so 1.5•9.8•200=2940
Or C

Answer 2

Gravitational potential energy gained by the bird is 2940 Joules.

Step-by-step explanation:

It is given that,

Mass of the bird, m = 1.5 kg

Height from the ground level, h = 200 m

We have to find the gravitational potential energy gained by the bird. The gravitational potential energy is possessed due to the position of an object under the action of gravity. Mathematically, it can be given by :

PE = mgh

`PE=1.5\ kg* 9.8\ m/s^2* 200\ m`

PE = 2940 joules

So, the correct option is (c) " 2940 Joules ". Hence, this is the required solution.
