On a smooth table two particles of mass m each, travelling with a velocity v$_0$
in opposite directions, strike the ends of a rigid massless rod of length l, kept
perpendicular to their velocity. The particles stick to the rod after the collision.Find
the tension in rod during subsequent motion.
I tried to conserve momentum ,
2mv$_0$R = I$\omega$
2mv$_0$R = (2mR$^2$ ) $\omega$
got the angular velocity of combined motion a ($v_0$)/(R)
But how to proceed.
