A.
disperses the force of the impact throughout the wood.

exerts an equal and opposite force back on the hammer.
C.
creates a balanced force.
D.
is stuck and won't go any further into the wood.

Answer 2

Alright. Think about Newton's third law. D can be eliminated, since the nail IS moving. A, while possibly true, doesn't really have anything to do with WHY the hammer bounces back. if you need more help, let me know! :D

Answer 3

umm i do

Answer 4

Okay. Newton's third law states that:
Every action has an EQUAL and OPPOSITE reaction.
Think about the answer choices. The hammer goes ''down'' and hits the nail. When it does, it bounces UP, which is the OPPOSITE reaction it had in the beginning. :D
