Question

What is the gravitational potential energy of a 85 kg person standing on 1 point the roof of a 10-storey building relative to the roof? (Each storey is 2.2 m)

Answer 1

Answer:

18326 J

Explanation:

length of each storey=2.2m

10 storey=22m

potential energy = work at a certain height

= mass×acceleration due to gravity×height

=85×9.8×22

18326 J

Answer 2

• Explaination:
• Given What is the gravitational potential energy of a 85 kg person standing on 1 point the roof of a 10-storey building relative to the roof?
• So potential energy is given by m . g . h
• Now m = 85 kg
• So g = 9.8 m / s^2
• Also h = 2.2 x 10 = 22 m
• Therefore gravitational potential energy will be 85 x 9.8 x 22
•                                                                              = 18,326 J
