Collision + observation

Classical Mechanics Level 5

A particle of mass \(m\) strikes with a rod of mass \(m\) at its one of end as shown in diagram with \(e = 0\), without sticking to the rod. If we observe the rod and particle from the point \(A\) on the rod, then:

\((A)\) Angular momentum of rod and particle will be conserved just before and just after collision.

\((B)\) Linear momentum of rod and particle will be conserved.

\((C)\) Observed motion of rod after collision will be pure rotation.

\((D)\) Observed motion of particle will be straight line after collision.
