    The elastic potential energy stored in the bungee cord = 20 J

    Explanation:

    potential energy: This is the energy possessed by a body due to its position. The S. I unit of energy is Joules. The mathematical expression for elastic potential energy is given below

    E = 1/2ke² ... Equation 1

    Where E = elastic potential energy of the spring, k = force constant of the spring, e = extension

    Given: K = 10 N/m, e = 2.00 m

    Substituting these values into Equation 1

    E = 1/2 (10) (2) ²

    E = 5*4

    E = 20 Joules.

    Therefore the elastic potential energy stored in the bungee cord = 20 J
