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?

Answer 1

The potential energy of the brown bear can be calculated using the formula:

Potential energy = mass x acceleration due to gravity x height

Here, the mass of the brown bear is 75 kg, acceleration due to gravity is 9.8 m/s^2, and the height climbed by the bear is 15 meters.

Therefore, the potential energy of the brown bear is:

Potential energy = 75 kg x 9.8 m/s^2 x 15 m
= 11,025 joules

So, the potential energy of the brown bear is 11,025 joules.
