Five coins on a table
Classical Mechanics
Level
3
Of five identical coins (they are circular), four are placed on vertices of a regular hexagon in above fashion. Left one moves with horizontal velocity \(24\text{ ms}^{-1}\), to collide with coin on bottom edge along the line joining their centers.
Find the magnitude of velocity with which the coin on top-left edge leaves the hexagon (horizontal velocity, to be precise*).
\(\textbf{Details and Assumptions}\)
Consider all surfaces to be smooth.
Consider all collisions to be elastic.
Answer in SI Units.
