PE=1/2 k x^2
and c is obviously zero, since x is zero.
A spring has a force constant of 590.0 N/m.
(a) Determine the potential energy stored in the spring when the spring is stretched 3.77 cm from equilibrium.
(b) Determine the potential energy stored in the spring when the spring is stretched 3.26 cm from equilibrium.
(c) Determine the potential energy stored in the spring when the spring is unstretched.
