1. The problem statement, all variables and given/known data A 36 kg mass is placed on a horizontal frictionless surface and then connected to walls by two springs with spring constants k1 = 3 N/m and k2 = 4 N/m. What is the frequency, f (in Hz), of oscillation for the 36 kg mass if it is displaced slightly to one side? 2. Relevant equations 3. The attempt at a solution So, I wasn't sure if the spring constant added linearly or if something crazy happened. If it did then I was thinking it would be possible to plug in some numbers into the energy equations. From there plug it into the SHM equations. I'm not sure if that works at all though. Thanks!
