Question

An owl has a mass of 4.00 kg. It dives to catch a mouse losing a total of 800.0 J of GPE. How high was the bird to begin with?

Answer 1

we know that U=mgh

where U=energy

m=mass

g=gravitational force

h= height

m=4kg

U=800 joules

g=9.8ms^-2

U=mgh

h=mg÷U

4×9.8÷800

1÷20

0.05m ANSWER.
