Let's define potential energy:
By definition, the potential energy is given by:
Ep = m * g * h
Where,
m: mass
g: gravity
h: height.
The potential energy change is:
Delta Ep = Epf- Epi
Delta Ep = m * g * hf - m * g * hi
Delta Ep = m * g * (hf - hi)
The, we have
Substituting values:
Delta Ep = (4.5) * (9.8) * (25 - 5)
Delta Ep = 882 J
Answer:
the eagle gain:
Delta Ep = 882 J
