    7350 J

    Explanation:

    Gravitational Potential Energy: This is defined as the energy possessed by a body due to it's position in the gravitational field. The S. I unit is Joules (J).

    Applying,

    E. p = mgh ... Equation 1

    Where E. p = Gravitational potential Energy, m = mass of the object, h = height of the object above the surface of the earth, g = acceleration due to gravity.

    Given: m = 2.5 kg, h = 300 m

    Constant: g = 9.8 m/s²

    Substitute these values into equation 1

    E. p = 2.5 (300) (9.8)

    E. p = 7350 J.
