A light elastic string of natural length land modulus of elasticity 2 is stretched by an extension

Question:

A light elastic string of natural length land modulus of elasticity 2 is stretched by an extension x, by means of a force T, causing the string to gain elastic potential energy (EPE). Find the unknown value in each case.

a. λ = 50N, x = 0.5m, I = 1.5m. Find the energy stored in the string.

b. EPE = 100J, λ = 60N, I = 1.2m. Find the extension of the string.

c. EPE = 50J, x = 0.8 m, I = 1.6m. Find the modulus of elasticity.
