it will be 0.5kx^2 where k=9.17&x=0.133

By definition the work needed to stretch a sping having elastic constant k with the dispăplacement x is equal to the elastic potential energy variation W =k*x^2/2 = 9.17*0.133*0.133/2 =0.081 J

This problem is in the Energy Conservation in Oscilatory Motion section of the textbook why is that?

this is because the work we do on the spring gets converted to the potential energy of the spring & gets conserved..and can be used when needed:)
