I'm having some trouble with some relatively basic Simple Harmonic Motion problems. First off, when determining the energy of an object do we need to take into account it's height of above the ground? At t=0 it is at 0.50m(highest) and at t=0.5 it's at 0.10m (it's lowest). The maximum velocity would take place at 0.3m, would I have to take into account the potential energy it has from just hanging there or do I just take into account it's energy from it's velocity? Also what does this "5. What is the value of the frequency in Hz (no units with your answer) where you expect to see a maximum in the amplitude for your sketch of amplitude of the motion of the object as a function of frequency." even mean. I have no idea what the question is even asking. Thanks in advance.
