A 2.85 kgkg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0350 m. The spring has force constant 865 N/mN/m. The coefficient of kinetic friction between the floor and the block is 0.390. The block and spring are released from rest and the block slides along the floor. 1)What is the speed of the block when it has moved a distance of 0.0200 mm from its initial position? (At this point the spring is compressed 0.0150 m.)
