Theodore Mueller · Answer 1

Elastic potential energy is the energy that is stored from the deformation of an object that is elastic like a spring. It is calculated by one half of the product of the spring constant and the square of the displacement. We do as follows:

PE = kx^2/2

PE = (1400) (2.5-1) ^2 / 2

PE = 1575 J
