A 0.230-kg block along a horizontal track has a speed of 1.70 m/s immediately before colliding with a light spring of force constant 48.0 N/m located at the end of the track. What is the spring's maximum compression if the track is frictionless?

mv²/2=kx²/2

x=v•sqrt(m/k) =1.7•sqrt(0.23/48)=0.12 m
