Unformatted text preview: Excel found the best fit line to be y=.026x.0811 VI 3 Using Linest in excel I found the slope and intercept and the uncertainty. Slope0.0263490.81136intersept Uncertainty in slope 0.00035 0.018321Uncertianty in intercept Using the equation The measured angle 44 with the uncertainty of +/ 1 VI4 VI5 VI6 6. The reason that we graphed h/D vs. D rather then h vs. D because h vs. would not give us a straight line and we would not be able to calculate the initial velocity. The h/D vs. d is a straight line and we can find the initial velocity and the intercept we need to find the launch angle....
