Question 21

A high-precision seismometer contains a sensor mass of 0.080 kg suspended from a support by two identical light vertical springs connected in parallel. Each spring has a stiffness of 9.0 N m-1. When the sensor is disturbed, the mass undergoes vertical oscillations of small amplitude. What is the frequency of these oscillations?
