Question

The potential energy of a 45 kg cannon ball is 15000 J. How high was

the cannon ball to have this much potential energy?

Answer 1

33.3

Step-by-step explanation:

Potential energy =

mass × gravitational field strength × height

rearranged =

`(potential \ energy)/(mass \: * gravity) = height`

`(15000)/(45 * 10)`

(The earths gravitational field strength will always be 10)

=33.33333 recurring to 1dp its 33.3
