Answer:
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
