Using a 2-D collision experiment:(adsbygoogle = window.adsbygoogle || []).push({});

A marble is launched off a track and travels 28cm before it hits the floor.

A marble is launched off a track and hits another marble at the end of that track, where both hit the floor. One lands 13cm away at 44° from the perpendicular and the other lands 22cm away at 41° from the perpendicular.

I did the math and got the the correct answer, but then there is another question that asks "Explain why the displacement represents acceleration".

I really have no idea how these to have anything in common. I know that the collision causes energy transfer causing the balls to go in a slightly different direction. Does anyone have any hints?

Thanks.
