Question

Your 2.4kg physics book lies on a shelf which is 1.5 meters off the ground . defining zero to be the ground level. how much gravitational potential energy does the book have in joules?

Answer 1

Gravitational potential energy of the book in Joules is 35.32

Step-by-step explanation:

Gravitational potential energy = Mass x Acceleration due to gravity x Height

P.E = mgh

Mass, m = 2.4 kg

Acceleration due to gravity, g = 9.81 m/s²

Height, h = 1.5 m

P.E = mgh

Gravitational potential energy = 2.4 x 9.81 x 1.5

Gravitational potential energy = 35.32 J

Gravitational potential energy of the book in Joules = 35.32
