Question

An owl has a mass of 4 kg. It dives to catch a mouse losing 800 J of gravitational potential energy. How high was the bird to begin with?

EXPLAIN PLZ

Answer 1

Answer:

20.4 m

Explanation:

Potential energy= Mass×Acceleration due to gravity ×Height acceleration due to gravity =9.8 m/s² for earth

800=4×9.8×h

h is approximately equal to 20.4 m

Answer 2

Answer:

The height of the bird was $20.40m$

Explanation:

It is the energy that an object has as a result of its position in relation to other objects. Definition of Potential Energy Potential Energy Formula Unit of Potential Energy Potential Energy Types Potential Energy Examples

we know that Potential energy= Mass×Acceleration due to gravity ×Height

• acceleration due to gravity $=9.8 m/s²$

we have,

$m=4kg$

$g=9.8m$

apply ,

$\text { Mgh }=4 \times 9.8 h=800$

$h\frac{800}{4 \times 9.8} =\frac{200}{9.8} \\=20.40 \mathrm{~m}$
