Answer:
4.225 J
Explanation:
Elastic Potential Energy: This is the potential energy stored in an elastic material.This also the energy required to stretch an elastic material. The S.I unit is Joules.
Mathematically it is expressed as
E = 1/2ke²....................... Equation 1
Where E =elastic potential Energy, k = spring constant, e = extension.
Given: k = 5.0 N/m, e = 3.93-2.63 = 1.3 m.
Substitute into equation 1
E = 1/2(5)(1.3)²
E = 8.45/2
E = 4.225 J.
Thus the Elastic potential Energy = 4.225 J.
