    What was the mistake in solving for the speeds of two marbles after a collision?

    Thank you guys, and I'll fix that in the future. I ended up finding the correct answer and it was an algebra mistake.

    Sorry it was the answer to the second question. Also going back and re-plugging in the numbers I got 2.22, but it's still wrong.

    Solved equation 1 for v1f and then substituted into equation 2 and solved for v2f. Got 2.22 as the answer, but it said the answer is incorrect.
