Moved from a technical forum, so homework template missing.

A block with initial speed 3 meter per second compress the spring in a frictional surface. Given that the spring constant k = 11000 N/M, mass of the block= 2.5 kg, coefficient of kinetic friction= 0.4. Calculate distance d that block travel until it momentarily stopped.

This is my method

initial KE = final PE + Work done by friction

However, is it possible to use force to calculate distance d since the acceleration of block depend on the extent of how much the block compress the spring.
