Assume motion in one dimension. You want
to determine the mass of an object, by
applying a known force F to it and measuring
the objects acceleration a. However, there is
also an unknown resistive force -f acting on
the object, so that the net force is Fnet = F - f.
In addition, your force sensor drifts slightly, so
that its readings are not very accurate. You
therefore make 4 measurements. For F = 1, 2,
3, and 4 N you measure the accelerations
6.26, 12.21, 19.26, and 26.39 m/s².
respectively.
Enter these data into an Excel spreadsheet
and produce a graph of F versus a. Add a
trendline, and Choose "Linear", "Display
equation on chart". Do NOT set the intercept
equal to zero. Format the trendline label so
that it shows 3 decimal places.
Assume F f = ma, or F = ma + f.
The y-intercept of the trendline represents
the unknown resistive (frictional) force. What
is the magnitude of this force in N?
Enter a number with 3 digits behind the
decinal point.
