Please someone have an answer to this one...I'm stuck!

"EXPLAIN USING NEWTONS THIRD LAW OF MOTION, what will happen when a person standing on a skateboard or rollerblades, throws a heavy concrete block as fast as they can at a person standing 10 feet in front of them"

I just don't understand it and it's the last problem on my homework.

I think that that due to Newton's Third Law, then when you throw the block (and it's catcher), it will go a certain distance, say x. However, because the force you used to throw the block also acts back on you, then in theory, you will go backwards the same distance x that the block went originally.

Get it?

HERES AN IDEA!

Go stand on a skateboard and throw a brick.

See how it works?

I know he already explained it but now I feel like doing this...God. You're 16 and in physics. I'm a senior in highschool and avoided that class all togther.
