Are you familiar with Newton's 3rd Law? If not: http://www.physicsclassroom.com/class/newtlaws/Lesson-4/Newton-s-Third-Law :)

Actually, @CShrix, maybe since the board breaks you can't say for sure?

Nope! The law always applies. Whether it breaks or not is a different matter. If a fly hits a bus that is driving with a certain force and is squished upon contact, it still hits the bus with the same force as the force that the bus hits the fly.
