A block of mass 2.00 kg is placed against a horizontal spring of constant k = 775 N/m and pushed so the spring compresses by 0.0800 m.
 
(a)
What is the elastic potential energy of the block-spring system (in J)?
 J
(b)
If the block is now released and the surface is frictionless, calculate the block's speed (in m/s) after leaving the spring.
