Problem
A 0.25 kg mass hangs from a vertical ideal spring with spring constant 30 N·m⁻¹ and is at rest in its equilibrium position. The mass is then pulled straight down an additional 0.050 m and released from rest. Taking upward as the positive direction, determine the instantaneous acceleration of the mass at the moment of release.
