Question

A 2 kg mass hangs from a movable pulley. A string over the pulley has one end fixed to the ceiling and the other attached to a fixed-end spring of 200 N/m. Find the frequency of small vertical oscillations, in Hz.

If the mass moves y , the spring stretches 2 y and the tension is 2 k y . The mass feels 2 T = 4 k y , so k e ff ​ = 4 k = 800 , ω = 20 , f = 3.18 Hz.
