# Calculate Velocity Of Train At Instant It Strikes Buffers And Strain Energy Gained By Buffers

Question

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.

Summary

The question belongs to Physics and it discusses about calculation of strain energy gained by buffers and velocity of train at instant it strikes buffers.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
