At the last problem there were 2 mathematical possible solutions. (w^2-100)^2=20^2 => w^2-100=+-20 (+ or -). So w=10.9 rad/s or w=8.9 rad/s. These are 2 diffrent solutions for the same problem. So the spring will rezonate at 2 diffrent frequencies.

what would happen in space, in a vacuum where there is no air molecules and no other friction?  Would a spring oscillate forever?
