Ball Drop Phenomenon: Designing a Multi-Ball System for Maximum Elevation

[emadkarimianrad]

sombodyyyyyyyyy hellllllllllp me

Astroblaster:
When a large ball is dropped, with a smaller one stacked on top of it, onto a hard surface, the smaller ball will often rise much higher than it would if dropped onto the same surface by itself while the larger ball hardly bounces at all. Investigate this phenomenon and design a multiple-ball system, using up to 4 balls, that will reach the greatest elevation of the top ball.

Have a look at these to get some idea of what is happening..
