a block of mass 0.428 kg0.428 kg is hung from a vertical spring and allowed to reach equilibrium at rest. as a result, the spring is stretched by 0.626 m.0.626 m. find the spring constant. n/mn/m the block is then pulled down an additional 0.365 m0.365 m and released from rest. assuming no damping, what is its period of oscillation? ss how high above the point of release does the block reach as it oscillates?
