Problem
Two light springs of force constants 100Nm−1 and 150Nm−1 are connected in series to support a 0.25kg mass. The mass is displaced by 0.04m from the equilibrium position and released.
(i) Find the effective force constant of the spring system.
(ii) Calculate the magnitude of the restoring force acting on the mass at this displacement.
