1\,\text{kg}

block slides on a horizontal rough table with an initial speed of

4\,\text{m\,s}^{-1}

. The coefficient of kinetic friction between the block and the table is

0.25

. The block compresses a horizontal spring of force constant

200\,\text{N\,m}^{-1}

and comes momentarily to rest. Calculate the maximum compression of the spring.
