A 2.50 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0300 m. The spring has force constant 840 N/m. The coefficient of kinetic friction between the floor and the block is .40. The block and spring are released from rest and the block slides along the floor. What is the speed of the block when it has moved a distance of .0200 m from its initial position (at this poing the spring is compressed 0.0100m)
