Answer :
Given:
The mass of the brown bear is m = 75 kg
The height of the tree is h = 15 m
To find the potential energy.
Explanation:
The potential energy can be calculated by the formula
[tex]P.E.\text{ = mgh}[/tex]Here, g = 9.8 m/s^2 is the acceleration due to gravity.
On substituting the values, the potential energy will be
[tex]\begin{gathered} P.E.\text{ = 75}\times9.8\times15 \\ =11025\text{ J} \end{gathered}[/tex]Thus, the potential energy of the bear is 11025 J
