Step-by-step explanation:
Gravitational potential energy is:
PE = mgh
Given PE = 96000 J and m = 80 kg:
96000 J = (80 kg) (9.8 m/s²) h
h ≈ 122 m
Round as needed.
The answer is C something like a step - by - step explanation
So, since it is square, we are going to take the square root of 121 which is 11. And since fencing goes around something, that means we have to find the perimeter. So since all four sides are the same length, we can just multiply 11 by 4 to get 44 meters of fencing
