A rod `AB` of mass `M` and length `L` is lying on a horizontal frictionless surface. A particle of mass `m` traveling along the surface hits the end `A` of the rod with a velocity `v_(0)` in a direction perpendicular to `AB`. The collision is completely elastic. After the collision the particle comes to rest. Find the ration `m//M`.
