Question
A mass weighting 48 lbs stretches a spring 3 inches. The mass is in a medium that exerts a damping
force of 20 lbs when the mass has a speed of 4 ft/sec.
Suppose the object is displaced an additional 6 inches and released.
Find an equation for the object's displacement, u(t), in feet after t seconds.
u(t) =
Use the convention: If the displacement is upward then u < 0
