The Big Push: data and assignment

Presenting the Data from the Car Push!
Here is your data analysis assignment.
•Using excel calculate the acceleration for each trial.
•Plot an appropriate graph of Force and Acceleration:
        Q: What does the trend line tell you? 
•The mass of my car  (con mio) is about 3000lbs (1400kg).
        Q: Is this consistent with the data?  If it is not, propose hypotheses explaining what went wrong.
                i.e.   What assumptions did we make that might be erroneous?
                        Where is the likely sources of error?
                         If you think we were pushing up hill can you calculate what angle would account  
                         for our discrepancies?  do it if you can.
•Friction/Resistive forces: Can you measure friction from our data? if you can try.
•What else can you make of our results?
•What should we have done differently?
