Question

A 95,000g refrigerator is located on the 70th floor of a skyscraper (300 meters above the ground) What is the

potential energy of the refrigerator?

Answer 1

285 kJ

Step-by-step explanation:

potential energy

= m g h

= 95,000 g × 10 m/s² × 300 meters

= 95 kg × 10 m/s² × 300 meters

= 950 kgm/s² × 300 meters

= 285,000 J

= 285 kJ
