1 Point
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

Answer 1

C. 573.3 J

Step-by-step 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
