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 11,225 J b 12,523 J c 10,500 J d 11,025 J
The potential energy (PE) of an object can be calculated using the formula:
PE = mgh
where m is the mass of the object, g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height.
In this case, the mass of the brown bear is given as 75 kg and the height climbed is 15 meters.
PE = (75 kg) * (9.8 m/s^2) * (15 m)
= 11,025 J
Therefore, the brown bear's potential energy is 11,025 J.
The correct answer is d) 11,025 J.
