A block of mass \( 1 \mathrm{~kg} \) hangs without vibrating at the end of a spring with a force constant \( 1 \mathrm{~N} / \mathrm{cm} \) attached to the ceiling of an elevator. The elevator is rising with an upward acceleration of \( g / 4 \). The acceleration of the elevator suddenly ceases. What is the amplitude of the resulting oscillations.
