Test wagon of waste has total combined mass of 10 tonne.

Test involves hitting the wagon with a linear velocity of Vm/s

Retarding mechanism of buffer stop has spring constant of 100 x 10³N/m and collision forms max compression of 700mm

- Calculate velocity of wagon upon impact.

Following calculations are needed too:

- Magnitude of energy lost during collision up to and including first compression.

- Deceleration of wagon during compression (assuming its constant)

- Total energy released by system (assuming total bounce back displacement is 1.55m)
