A 2.50-kg block on a horizontal floor is pushed against a horizontal spring that is initially compressed 0.0300 m. The spring has force constant 900 N/m. The coefficient of kinetic friction between the floor and the block is ??=0.30. The block and springare released from rest, and the block slides along the floor. a.What is the speed of the block when it has moved a distance of 0.0200m from its initial position? (At this point the spring is compressed 0.01 m.) b.What distance does the block travel from its initial position to where the block finally stops? (The block leaves the spring when the spring is unstretched or uncompressed)

Question
A 2.50-kg block on a horizontal floor is pushed against a horizontal spring that is initially compressed 0.0300 m. The spring has force constant 900 N/m. The coefficient of kinetic friction between the floor and the block is ??=0.30. The block and springare released from rest, and the block slides along the floor.
a.What is the speed of the block when it has moved a distance of 0.0200m from its initial position? (At this point the spring is compressed 0.01 m.)
b.What distance does the block travel from its initial position to where the block finally stops? (The block leaves the spring when the spring is unstretched or uncompressed).
