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?
a
10,500 J
b
12,523 J
c
11,225 J
d
11,025 J
d. 11,025 J
The potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s^2), and h is the height the object is at.
Given:
m = 75 kg
h = 15 m
g = 9.8 m/s^2
PE = 75 kg * 9.8 m/s^2 * 15 m
PE = 11,025 J
Therefore, the brown bear's potential energy when he is 15 meters up the tree is 11,025 J.
