Is newton's third law valid for rigid bodies? Say, if we have a bullet hit on a rod which is vertically placed on a rough floor. Friction is just sufficient sp that the rod rotates and does not slide. Just before collision the bullet makes an angle of 45 deg with the horizontal.
We have to find $\omega$ after collision.
Will the bullet exert an impulse on the rod which is equal to the impulse exerted by the rod on the bullet?
