    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
