Particle-Rod Collision: Rotation or Translation?

[amk_dbz]

A particle hits a rod at one of its end in space.
Now will the rod rotate or translate or do both...What part of the force goes into translation/rotation ??
If the above scenario happens in air, what will differ?

There are several things to consider--whether this is an elastic or inelastic collision and what angle the particle strikes the rod.

Regardless, conservation of linear and angular momentum apply for the system as a whole, so if the particle doesn't come in straight along the length of the rod, the rod's going to rotate after collision.

But why would it rotate and not translate??
(assume elastic collision and the velocity of particle is perpendicular to length of rod)

It's going to do both. Angular momentum and linear momentum are conserved quantities.

Ok, i seem to get it now. Just wasn't sure.
Thank You for your Help.
