Potential energy is the energy that is stored in an object due to its position relative to some zero position.  It is calculated by the expression as follows:

PE = mgh
PE = 25 (9.8) (3)
PE = 735 J

Hope this answers the question. Have a nice day.

Explanation:

Potential energy is the energy obtained by a substance due to their position.

Mathematically,      P.E = mgh

where     m = mass

               g = acceleration due to gravity = 9.8 m/s

               h = height

Since it is given that mass is 25 kg and height is 3 m. Hence, calculate the potential energy as follows.

                               P.E = mgh

                                      = [tex]25 kg \times 9.8 m/s \times 3 m[/tex]

                                      = 735 kg/s

Thus, we can conclude that potential energy for the given case is 735 kg/s.
