The weight of an empty railway wagon is 400 kN. On loading it with goods weighing 600 kN, its spring gets compressed by 200 mm. (a) Calculate its natural period of vibrations when the railway wagon is (i) empty and (ii) loaded as above. (b) It is set into natural vibrations with an amplitude of 120 mm when empty. Calculate the velocity of the railway wagon when its displacement is 40 mm from statically equilibrium position.
