For part (2), am I right in thinking that the following are the forces acting on the particle: W=-mgi R=rxi H=k(l-l0)s note the x term in R has a dot on the top (ie function of velocity I think

Hi All This is my first post and I was hoping that someone could help. I have the following attached question regarding a linear damping model (in this case a seismograph). (1) Draw a force diagram. If W=weight, R= air resistance, and H= spring force, then I get W pointing down and both...
