A 15 tonne wagon travelling at 3.6 ms is brought to rest by a buffer (a spring) having a stiffness of 7.5x10 Nm. Assuming that the wagon comes into contact with the buffer smoothly without rebound, calculate the compression of the buffer if there is a constant rolling friction force of 800 N. A 15 tonne wagon travelling at 3.6 ms is brought to rest by a buffer (a spring) having a stiffness of 7.5x10 Nm. Assuming that the wagon comes into contact with the buffer smoothly without rebound, calculate the compression of the buffer if there is a constant rolling friction force of 800 N.
