Also, using your data from Lab 4 (pulling the cart with a hanging weight): Compare your measured accelerations to the predictions fromn the two models we identifed in class as “B” and “C”.

Model B: gm_1_/(m_1+m_2)

Model C: g(m_1 - mu m_2)/(m_1 + m_2)

Calculate the fit score S for each model.

sum of squared acceleration residuals

where aim is the ith measured acceleration and aic is the ith calculated acceleration.  Answer the questions:

  • Does either model adequately explain the observations?
  • Do our results distinguish between the models?
