Question

What is the gravitational P.E of a person 61.2 kg standing on the roof of a 10 stories building on tenth floor

Answer 1

Answer:

Gravitational P.E = mass×earth's gravitational pull×height

=61.2×9.8×10

=5997.6 J

Explanation:

Formula is G =m×g×h

G = gravitational potential energy

m=mass (in kg)

g=gravitational pull of earth (always 9.8 m.s^-1)

h= height above the ground (in m)

answer is in Joules (J)

J= joules. Unit of measurement for energy.
