How much additional work is done by the spring

Reference no: EM13530949

A spring with a spring constant of 42.0 N/cm has a block attached to one end and the other end is fixed.

How much work does the spring do on the block if the spring is stretched from relaxed length by 15.2 mm as the block is moved?

How much additional work is done by the spring if it is stretched by an additional 15.2 mm?
