WILL MARK BRAINLIEST!!!!!

Explanation:
gravitational potential energy = mass x gravitational field strength x height
mass = 60 kg
height = 30 m
let's take the rounded up version of the gravitational field strength = 10 N / kg
so let's just substitute everything in the equation
gravitational potential energy = 60 x 30 x 10
= 18000 J
hope this helps bro
