## Homework Statement

i am stuck on part c

how do i find work with out using the spring constant

## Homework Equations

work equals force parallel times displacement at which the force is acted during...

Work done by spring = .5 kx^2

Work = delta K

but delta K = 0 because the table top is frictionless

Work = delta U

delta U = 0 in this situation correct?

## The Attempt at a Solution

so I'm stuck...

i think it might be zero but .5 kx^2 would not give zero now would it...
