A spring with spring constant 141 N/m is used to pull a 336 N wooden block horizontally across a tabletop at constant velocity. The coefficient of kinetic friction between the block and the table is 0.33. By how much does this spring stretch from its equilibrium length (in meters)?

hope this helps.
