It takes 25N of force to compress a very light spring 19cm. The spring is placed parallel to a table and its ends are firmly attached to the wall and to a 210-g wood block . The coefficient of kinetic friction between the block and the table is 0.31 . The spring is compressed a second time to 19cm and then released from rest.

How far beyond its equilibrium position will it stretch on its first cycle? Express your answer to two significant figures and include the appropriate units.
