    Answer: 0.04 Newton

    Explanation:

    Work is done when force is applied on an object over a distance. It is measured in joules. Workdone = Force x distance

    Since, Work = 107 joules

    Force = ? (Let unknown value be Z)

    Distance = 2721 metres

    Workdone = Force x distance

    107J = Z x 2721metres

    Z = (107J / 2721 metres)

    = 0.039 Newton (approximately 0.04N)

    Thus, 0.04 Newton is the force applied by the Tyrannosaurus rex.
