Simple pendulum and vertical block-spring oscillator inside an elevator car.
Simple pendulum and vertical block-spring oscillator inside an elevator car.
A simple pendulum of length \(L\) and a vertical block-spring oscillator with mass \(m\) and spring constant \(k\) are both undergoing small-amplitude simple harmonic motion inside an elevator at rest near Earth's surface. The elevator cables suddenly snap, placing the elevator into free fall with a downward acceleration of magnitude \(g\). Which of the following correctly pairs the subsequent oscillatory behavior of the simple pendulum with that of the block-spring oscillator, as observed from the reference frame of the elevator car?
