Kinetic energy of block at bottom = m g h
that goes into compressing the spring
m g h = (1/2) k x^2
solve for x^2 and x
A 500g block is released from rest and slides down a frictionless track that begins 2m above the horizontal. At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with a spring constant of 20.0N/m. Find the maximum distance the spring is compressed.
