A 2.35 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0400m. The spring has force constant 875 N/m. The
coefficient of kinetic friction between the floor and the block is 0.45. The block and spring are released from rest and the block slides along the floor.

A. What is the speed of the block when it has moved a distance of 0.0100m from its initial position? (At this point the spring is compressed 0.0300m.)
