A5 kg bird has 15,000 j worth of gpe. how high must it be above the ground?

306.12m

Explanation:

Gravitational Potential Energy or GPE can be computed by the formula:

PEgrav= mgh

where:

PEgrav = GPE (J or kg.m²/s²)

m = mass (kg)

g = acceleration due to gravity (m/s²)

h = height (m)

So all you need to do is fill in what you know and solve what you don't know.

In this case the following are given:

m = 5kg

g = 9.8 m/s²

h = ?

PEgrav = 15,000J or 15,000kg.m²/s²

15,000 kg.m²/s = (5kg)(9.8m/s²)(h)

The answer is then 306.12m
