A block of mass m is connected to a spring the other end of which is fixed. There is also a viscous damping mechanism. The following observations have been made about the system:
1) if the block is pushed horizontally with force = mg, the static compression in the spring is "h"
2) the viscous resistive force = mg if the block moves with a known speed "u"
a) Write the differential equation governing the horizontal oscillation of this mass in terms of m,g,h,u.
b) if u is known to be = [tex]3\sqrt(gh)[/tex] what is the angular frequency of the damped oscillation?
