A 2.5 kg block collides with a horizontal spring of negligible mass and spring constant.

k=320 N/m. The block compress the spring by 8.5 cm from its rest position. How fast was the block going when it hit the spring if the frictional coefficient between the block and the horizontal surface is 0.40?
