1. The problem statement, all variables and given/known data A massless spring hangs from the ceiling with a small object attached to its lower end. The object is initially held at rest in a position yi such that the spring is at its rest length. The object is then released from yi and oscillates up and down, with its lowest position being 25 cm below yi. (a) What is the frequency of the oscillation? 2. Relevant equations SHM Equations: X=Acos(), etc. omega = sqrt(k/m) T = 2PI * sqrt(m/k) 3. The attempt at a solution a = w^2 * A ... w = 6.26, so f = 1 -- wrong obviously I'm relatively sure I need to find omega to get the frequency, but for some reason I simply can't get omega. Any help would be great, because I've been staring at it for about an hour. I'm sure I'm missing something really stupid.
