Step-by-step 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
=

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