A massless spring of length $l$ and spring constant $k$ is placed vertically on a table. A ball of mass $m$ is just kept on top of the spring. The maximum velocity of the ball is
Show Hint
Maximum speed in spring problems occurs at equilibrium position where potential energy converts fully into kinetic energy.
