SUMMARY
The discussion centers on calculating the work done by a spring with a force constant of 548 N/m attached to an 8 kg disk in uniform circular motion. The spring stretches by 4 cm, and the participant initially attempts to apply the centripetal force equation, concluding that the work done is zero due to the perpendicular nature of the centripetal force to the velocity vector. The participant evaluates various work values, ultimately recognizing that the work done by the spring does not contribute to the disk's kinetic energy in this scenario.
