The weight of an empty railway vehicle is 250 kN. On loading it with goods weighing 420 kN, its spring gets compressed by 29 cm. (a) Calculate its natural period of vibrations when the vehicle is (i) empty and (ii) loaded as above. (b) It is set into natural vibrations with an amplitude of 260 mm when loaded. Calculate the velocity and acceleration of the vehicle when its displacement is 90 mm from statically equilibrium position. Also calculate the maximum acceleration
