A train of mass 15000kg is brought to rest when striking the buffers of a terminus. The buffers consist of two springs in parallel as shown in Figure5(b).The spring constant of each spring is 120kN/m. The springs are compressed by 0.75m when the train is brought to rest. Assuming that there is no losses of energy due to the impact calculate:
(i) The strain energy gained by the buffers.
(ii) The velocity of the train at the instant it strikes the buffers.
Additional information
The problem related to Physics and it discusses about calculation of strain energy gained by buffers and velocity of train at instant it strikes buffers.
