massless vertical spring, with spring constant k$=980$N$/$m$,$ is attached to the floor and is compressed down $0\mathrm{.}2$m from its equilibrium position, which we take as the origin, x$=0.($a$)$What upward speed can it give to a m$=0\mathrm{.}4$kg ball $($which is just being put on the spring but not attached to it$)$ when released? $($b$)$ At what position relative to its original position $($spring compressed$)$ will the ball fly off the spring? $($c$)$ How high above its original position $($spring compressed$)$ will the ball fly?
