Suppose a rod is rotating about its center of mass, for simplicity consider it to be its geometric center(uniform density). At an instant a rigid ball is introduced near the rod so that it collides with the rod and the stick comes to rest(rotationally and translationally). Then can the ball be said to posses the equivalent linear momentum of the rotational(angular) momentum possessed by the rod initially. Also if the parameters are as below please tell me how to calculate the final linear momentum of the ball. mass of rod= x ,mass of ball=y,angular velocity of rod=v,arm distance from center where collision takes place=d.
