A mass and spring are arranged on a horizontal, frictionless table as shown in the figure below. The spring constant is $k=480\frac{N}{m},$ and the mass is $4\mathrm{.}1kg.$ The block is pushed against the spring so that the spring is compressed an amount $0\mathrm{.}32m,$ and then it is released. Find the velocity of the mass when it leaves the spring.

$\frac{m}{s}$
