Thank you, I will give it a go and see what i obtain. Theoretically i should obtain a smaller fraction of the initial height. When 3 is raised the component of height is smaller due to 3 having a 3M mass (mgh). What equation can i use to take into consideration the shifting of 2?

Thank you. How would I go about solving that question. Do you have any tips?

My teacher explained when giving the question to me that the question was not as easy as it looked and that there was a hidden side to it. The point that rcgldr makes seems to be along the lines of what my teacher was referring to. Is there any way of calculating the height after collision just...

It would be the same height, as there would be conservation of energy. The small gap means that some energy is lost in the collision. However the question says that all subsequent collisions are elastic.

Homework Statement Three small identical steel balls A,B and C are suspended by vertical threads of equal length from a horizontal support, with centres in a horizontal line and separated by a small gap. A is raised by a height 'h', with the thread taut, and released. All subsequent collisions...
