31PRACTICE PROBLEM
A spring-mass system lies on a horizontal disk initially at rest. The spring's free end is attached to the disk axle. The mass undergoes periodic motion with a period of 0.65 s. When the disk is spun at a certain frequency (mass not oscillating), the spring extends, and its length increases by 25%. Calculate the disk's rotation frequency in rotations per minute (rpm).
