A 2.75 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0320 m. The spring has force constant 850 N/m. The coefficient of kinetic friction between the floor and the block is 0.450. The block and spring are released from rest and the block slides along the floor. Part A What is the speed of the block when it has moved a distance of 0.0180 m from its initial position? (At this point the spring is compressed 0.0140 m.) Express your answer with the appropriate units.
