1. The problem statement, all variables and given/known data Two identical ice skaters are holding onto opposite ends of a very long spring with a spring constant of 650 N/m. While spinning in a circle, the skaters frequency of revolution is measured to be 0.85 Hz. What is the mass of the skaters? 2. Relevant equations F = kx 3. The attempt at a solution F = (650 N/m)x ?
