A homogenous rod of length,

l = x η

and mass

M

is lying on a smooth horizontal floor. A bullet of mass

m

hits the rod at a distance

x

from the middle of the rod at a velocity

v_{0}

perpendicular to the rod and comes to rest after the collision. If the velocity of the farther end of the rod just after the impact is in the opposite direction of

v_{0}

, then,
