A moving $4\mathrm{.}2$ kg block collides with a horizontal spring whose spring constant is $215\frac{N}{m}($see figure$).$ The block compresses the spring a maximum distance of $6\mathrm{.}5$ cm from its rest position. The coefficient of kinetic friction between the block and the horizontal surface is $0\mathrm{.}38.$ What is the work done by the spring in bringing the block to rest?
