Answer:
0.0928J
Explanation:
the pulling force of spring F=-kx
where x is the displacement from equilibrium position.
energy stored:

*** Its fine if you know nothing about calculus. Just apply the equation

where U is the potential energy of the spring***
put x=0.150,
×
= 0.0928J (corr. to 3 sig. fig.)
