1. The problem statement, all variables and given/known data A mass m at the end of a spring oscillates with a frequency of 0.83 Hz. When an additional 680-g mass is added to m, the frequency is 0.60 Hz. What is the value of me? 2. Relevant equations w = 2 pi f w^2 = k / m 3. The attempt at a solution m = .74725 kg I'll probably be adding a few more problems, as my textbook didn't come with a solutions manual. I wish it did.
