A 2.606 kg block is on a horizontal surface with ìk = 0.160, and is in contact with a lightweight spring with a spring constant of 577 N/m which is compressed. Upon release, the spring does 7.212E-1 J of work while returning to its equilibrium position.

Question

A 2.606 kg block is on a horizontal surface with ìk = 0.160, and is in contact with a lightweight spring with a spring constant of 577 N/m which is compressed. Upon release, the spring does 7.212E-1 J of work while returning to its equilibrium position.
I found the distance the spring was compressed-.05m
What is the velocity of the mass as it breaks contact with the spring?
i think i know how t do it but i kind of confused on how to get the energy of the fritional force

never mind i got the question:)
