1. The problem statement, all variables and given/known data Suppose the motion of a spring has natural frequency 1/2 and is undamped. If the weight attached is 32lb, write a differential equation describing the motion. 2. Relevant equations my''+ky=F_ocosωt 32y"+8y=? ω_o= (k/m)^.5 3. The attempt at a solution → .5=(k/32)^.5 → k=8 gamma=0 32y"+8y=? My problem is that I don't know how to find F_o or ω. Is this question referring to that of a no external force case? Or am I missing some equation that will help me find this?
