    98100 J

    Explanation:

    Energy due to position = Potential Energy

    Potential Energy = m*g*h

    Potential Energy = 1000 * 9.81 * 10

    Potential Energy = 98100 J

    Answer: 98,000 J

    Explanation: The total energy or mechanical energy is expressed in the following equation:

    ME = PE + KE

    PE = mgh

    = 1000 kg x 9.8 m/s² x 10m

    = 98000 J

    ME = PE - KE

    = 98000 J - 0 J

    = 98000 J
