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?

Gravitational potential energy of the book in Joules is 35.32

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
