Homework Help: Fnet Lab UGHH

  1. Dec 14, 2009 #1
    1. The problem statement, all variables and given/known data

    Okay so we did this lab at school a few days ago where we had a cart and pulleys with different amounts of weights. They used photogates. By doing this we got the acceleration of the cart (measured). I figured the "accelerative force of falling mass" by using the f=ma equation.
    It is looking for the Fnet force on the cart causing acceleration? would that be F = (M + m) acceleration ?

    2. Relevant equations


    3. The attempt at a solution
    i'm not sure...
