Question

A 75kg refrigerator is located on the 70th floor of a skyscraper (300m above ground). What is the potential energy of the refrigerator?

Answer 1

Step-by-step explanation:

potential energy = mgh

ATQ,

m=75kg, h=300m, g=9.8m/s²(if not given)(10 m/s² if given)

therefore, 75×300×9.8 = 2,20,500J.

hope this helps you.
