Question
e other spreadsheet, make a graph of the 'Position of Each Leading e Time at Each Leading Edge'. This will be a graph of the position of the picket fence versus time (x vs t) a. What should the shape of this graph be (straight line, parabola, circle, ellipse, hyperbola, etc.)? linear Do a quadratic fit to your graph. Turn in a copy of your graph of x vs. t with the quadratic fit plotted and the equation of the fit on the same graph. Write the fit equation below. acceleration, g, and compare it with the accepted value of the free-fall acceleration, g- 9.81 m/s by computing a percent error b. From the parameters in this equation, compute the c. From the parameters in the equation, compute the initial velocity voy and record it below. Is this a reasonable value for the initial velocity, or would you expect it to be zero? Explain.Explanation / Answer
You are on right path since you have done the linear fit.
For the quadratic fit, make one more column as t*t (t square). So now you have 3 columns. When you are going to plot curve this time,select column X as input for ‘y’ axis and select columns t and t-square as input for ‘x’ axis.
You will get fit equation of this form, x = at + b(t)^2 +c(intercept)
On comparing it with standard equation, s = ut + 0.5g(t)^2
a = u = initial velocity and 2b = g, so you can now do the required comparisons.
