Answer:
Correct answer: Ep₁ = 105.11 J
Explanation:
if we take as the zero reference point the bottom of the hole then the height difference is 11 m. Let named h₁ = 11 m
The formula for calculating potential energy is:
E p = m g h => mg · 9.0 m = 86 J => mg = 86/9
when we substitute this into the next formula we get
m g h₁ = 86/9 · 11 = 105.11 J
