A spring is stretched 10cm by a force of 3 N. A Mass of 2kg is hung from the spring and attached to a damper which exerts 3 N when the velocity = 5m/sec. There's more but I just need a little help setting it up. I don't understand how to find y (as in yu'(t)). Unless its just 3/5.

Just a few hints would suffice, I'm not asking you to solve these.

Thanks, Sean
Also, I'm sorry I also posted this in the physics homework area. oopsies.

have you tried using energy equations like:

m*g*height = (m*v^2)/2

I don't think that'll work since energy is not conserved (there is a dampening affect present).
 
uh then i don't understand your question properly... is there a drawing of it?
