0340m. The spring has force constant 855N/m.

A 2.90 kg block on a horizontal floor is attached to a horizontal spring that is initially compressed 0.0340 m. The spring has force constant 855 N/m. The coefficient of kinetic friction between the floor and the block is 0.35 . 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 0.0150 m

 from its initial position? (At this point the spring is compressed 0.0190 m)

(I got an answer 0.473 m/s but it still incorrect about the number or units of velocity)
