a squirrel with a mass of 4.5 kg sits on a branch that is 13 m off the ground.
what is its gravitational potential energy? the acceleration of gravity is 9.8
m/s2
o a. 743.0 j
o b. 986.23
o c. 573.3 j

C. 573.3 J

Explanation:

Given,

The mass of the squirrel, m = 4.5 Kg

The height of the branch where the squirrel is sitting, h = 13 m

The acceleration due to gravity, g = 9.8 m/s²

The gravitational potential energy on mass 'm' is given by the relation

                                  P.E = mgh  joules

Substituting the given values in the above equation

                                 P.E = 4.5 Kg x 13 m x 9.8 m/s²

                                       = 573.3 J

Therefore, the gravitational potential energy of squirrel is, P.E = 573.3 J

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.
