  Two identical bullets are fired one by one by a light rifle and another by a heavy rifle with the same force, which rifle will hurt the shoulder more and why?

Answer:

                  As both the bullets are identical and are fired with the same force. So, according to Newton's third law of motion, same force will be applied on both the rifles. With the application of same force, the light rifle will move more quickly in the forward direction, so it will hurt more to the shoulder. (2)
