Weightless spring of force constant

Reference no: EM13669231

A weightless spring of force constant 2.50 N/cm is 15.0 cm long when nothing is attached to it. It is now utilized to pull horizontally on a 12.5 kg box on a smooth horizontal floor. You observe that the box starts from rest and moves 96.0 cm through the first 1.60 s of its motion. How long is the spring through this motion?
