hi

i'm just wondering how the energy conservation works when throwing a ball into a cup with one bounce (using a surface)

please respond

Why do you choose a "cup" rather than a flat surface? If there is only one bounce (not multiple bounces inside the cup) then what difference would there be?

Energy conservation doesn't usually apply to 'real' collisions. Momentum is conserved, however.
The reason you have had no responses could be because your question is not specified enough. We don't respond to open questions as fully as to specific queries. You need to set the agenda of the thread.
