Question

A 75 kg brown bear climbs 15 meters up a tree to see if he can spot the best blueberry patch in the valley. What is the brown bear's potential energy?10,500 Jb11,025 Jc11,225 Jd12,523 J

Answer 1

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.

Step-by-step explanation:

The potential energy can be calculated by the formula

`P.E.\text{ = mgh}`

Here, g = 9.8 m/s^2 is the acceleration due to gravity.

On substituting the values, the potential energy will be

`\begin{gathered} P.E.\text{ = 75}*9.8*15 \\ =11025\text{ J} \end{gathered}`

Thus, the potential energy of the bear is 11025 J
