Homework Help: Showing momentum conservation

  1. Mar 7, 2012 #1
    Work out in detail the situation in which a moving all collides with a stationary ball in a totally elastic collision. Assume the balls have the same mass when doing this calculation. How does conservation of momentum show itself in this situation?

    p = mv F = ma p1i + p2i = p1f + p2f

    I assume the ball in motion stops and the ball at rest assumes the total velocity? Don't know how to describe this mathematically. Don't really understand how to explain it verbally either. Just remember it from good ole' marbles.

    I don't quite understand what you wrote down here.

    Because it is an elastic collision momentum will be conserved. What does the formula for conservation of momentum look like? Which variables will be 0 (and there for contribute to 0 momentum) before and after the collision?
