A student in Denver (altitude = 1 mile = 1609 m above sea level) brings a physics book of mass 1.3 kg to the top of a ten story building of height 26 m and holds the book over her head 151 cm above the roof. What is the gravitational potential energy Ug of the book?

    Potential energy is the energy of a body due to is virtue of rest.

    Potential energy is given as mgh

    g is a constant and it is 9.81m/s²

    And also the mass of the body is given as 1.3kg

    Now the height of the body is

    He took a book to a storey building of height 26m

    He still holds the book 151 cm (1.51m) above the house.

    The house is on an altitude of 1609m from the sea level.

    Total Ug with out the sea level is

    Ug=mgh

    Ug=1.3 * 9.81 * (26+1.51)

    Ug=350.84J

    Then, the potential energy due to the sea level is given as

    Ug=mgh

    Where g = 1/6371 m/s²

    Therefore

    Ug=mgh

    Ug=1.3 * 1/6371 * 1609

    Ug=0.328J

    Total energy = 0.328+350.84

    Ug=351.17J
