**Unformatted text preview: **Do a linear fit, , and double click the fit box to get the experimental
uncertainties. Put the fit parameters in laboratory workbook Table 2. QUESTION 3:What physical quantities do the slope and intercept
represent? Using a lab balance, weigh the cart, the card, the string and all the
masses. PLACE THE CART UPSIDE DOWN ON THE BALANCE. QUESTION 4: From your slope and intercept and the answer to Question
3, what are the total mass (mA+mB) and the force due to friction (f) for the
system? Include the experimental uncertainties of each. Physics 1020 Laboratory #4 Force and Acceleration Interpreting the Graph QUESTION 5: Write the total mass, including its experimental uncertainty
and units as recorded on the balance. QUESTION 6: Does your value of the total mass from the graph agree
with the measured total mass, within the experimental uncertainty?
Hint: Write down the range (minimum to...
