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...
