Concept

Problem: A spring is compressed against a 1 kg disk with radius 5 cm such that as the spring expands, its force is applied to the rim of the disk, allowing it to roll without slipping. If the spring has a force constant of 10 N/m, and it's compressed to 10 cm, how fast does the disk roll once the spring has expanded fully?
