A block with mass m $=7\mathrm{.}3$ kg is hung from a vertical spring. When the mass hangs in equilibrium, the spring stretches x $=0\mathrm{.}28$ m$.$ While at this equilibrium position, the mass is then given an initial push downward at v $=4\mathrm{.}8$ m$/$s$.$ The block oscillates on the spring without friction.
