POtential energy? Wouldn't it be 1/2 kx^2,

but x= F/k, so 1/2 kx^2= 1/2 k*F^2/k^2 and that can be reduced.

**Anonymous**, Monday, March 28, 2011 at 9:11amA 0.5-kg block attached to an ideal spring with a spring constant of 65N/m oscillates on a

horizontal frictionless surface. The total mechanical energy is 0.79 J. What is the greatest extension

of the spring from its equilibrium length?
