LAB REPORT FOR M4 EXPERIMENT: PROJECTILE MOTION VI-1 - This experiment was to calculate the projectile under with the influence. The data for V- 5 and the average and std deviation and h/d is in the table below. # D(cm) h1(cm) h2(cm) h3(cm) h4(cm) h5(cm) Averag e h std dev h h/d 1 30 -1 -1.4 -0.6 -1.1 -0.5 -0.92 0.370135 -0.03067 2 35 3.3 3.2 3.4 3.9 4.3 3.62 0.465833 0.103429 3 40 9.2 9.9 9.6 10.1 11.3 10.02 0.791833 0.2505 4 50 25.6 26.4 25.6 25.9 26.4 25.98 0.402492 0.5196 5 55 36 36.5 35.5 35.5 36.4 35.98 0.476445 0.654182 6 60 45.4 45.4 46 46.7 47.4 46.18 0.867179 0.769667 7 65 56.1 57 57.1 57.1 59 57.26 1.059717 0.880923 8 70 70.6 72.8 72.6 72.7 72.8 72.3 0.953939 1.032857 VI-2- I used excel to graph h/D vs. D D h/d 30 -0.03067 35 0.103429 40 0.2505 50 0.5196 55 0.654182 60 0.769667 65 0.880923 70 1.032857

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. Slope0.026349-0.81136-intersept Uncertainty in slope 0.00035 0.018321-Uncertianty in intercept Using the equation The measured angle 44 with the uncertainty of +/- 1 VI-4 VI-5 VI-6 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....
