A spring-mass system with m = 50kg and k = 4000N/m shown in Figure Q3(a).
If the mass is released from its equivalent position and results in simple
harmonic motion (SHM),
(i) Starting from a free body diagram, derive the equation of motion.
(ii) Determine the natural frequency.
(iii) Explain on how you can reduce the natural frequency of the spring-mass
system.
