Homework Help: Lab questions

  1. Oct 31, 2009 #1
    1. The problem statement, all variables and given/known data

    3. Tabulate the data for your measurements. Include all the measured constants you used for calculations. Show in detail the calculations of V0, V1, and V2 for an elastic collision with
    M1 = 200g and M2 = 300g.

    4. Tabulate the data for momentum and kinetic energy (KE) and show in detail the
    calculations of P0, P1, and P2 as well as KE0, KE1, and KE2, for an elastic collision with
    M1 = 200g and M2 = 300g.

    2. Relevant equations
    Any equations that deal with momentum and energy like p=mv and .5mv^2=e

    3. The attempt at a solution

    Ok, for a start is #3 even possible? All you know is that m2 is at rest. I think you need to know at least one more velocity before you can find out the other values right? I think the best you can do is solve v0, v1 and v2 as part of an equation. But then if you can't solve it how do you do #4?

    Thanks :)

    It all depends on what you measured. We cannot answer your question unless you tell us exactly what you did and how.
