Waves and Sound Vibrations Question Urgent Please Help!?!? 1. The problem statement, all variables and given/known data A mass suspended from the end of a spring vibrates up and down 25 times in 50s. What ar ethe frequency and period of the vibration. 2. Relevant equations F = 1/T T = 2(pie)3.14(squrroot)L/g 3. The attempt at a solution F = 1/T or is it: F = 50/25 F = 2Hz??? T = 2(3.14)(sqrroot) but what is the L???? I'm very confused and I need to finish this soon!
