A 2.50kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0350m . The spring has force constant 895N/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.
What is the speed of the block when it has moved a distance of 0.0150m from its initial position? (At this point the spring is compressed 0.0200m .)
