How do I model this function? (Damped Harmonic Motion)
.
Ok so I got this to be my equation, however, it yields an answer that doesn't match the one in the answer key which is 65.8cm. I'm...

So, would my c value be the Δx between the string and mass then? The 0.122m I calculated earlier? I'm so sorry for the myriad of...

Ok, so then would my Δx just be 10cm as that's the displacement from equilibrium that the spring is pulled and therefore it would be my...

Wouldn't it be at the unstretched end?

Would it be 0.1m + 0.122m?

So my net force would be equal to Fs = Δx*k in both directions, right? I'm writing it out now and I get a magnitude of 60N in both...

That's the equation my teacher's given us, so I'm assuming it's the one he wants us to use for problems like this. Thank you though!

I first solved for the extension of the spring when its at equilibrium w/ the mass. I got Δx = 0.122m. I thought that if I added this...

Would this be correct then? I have the centripetal force as the force of gravity and the force of tension b/c I think they'd both be in...
