• Data Analysis & Plots (6 points) Create a diagram, or annotate a photograph, to show how the apparatus is used to measure the quantities of interest.
Error: ± 0.005 m for horizontal distance, due to discrepancy in shooting the ball ± 0.001 m for vertical distance, due to the variations within the bolt’s movements θ ± δθ = 45 ± 0.001 vo ± δvo (original): 4.7 ± 0.3 vo ± δvo (new): 4.6 ± 0.5 Y = 0.28 ± 0.001 m X ± δX = 2.17 ± 0.005 m Analyze the collected data and present them using well-formatted plot(s).
• Result(s) and Comparison (6 points) State the final result(s) of your experiment clearly with an uncertainty estimate and measure- ment units. Use the appropriate number of significant figures for all reported measurements and associ- ated uncertainties. Compare your result to another relevant quantity. For example, you might compare your measurement to an accepted value or another another group’s value. Choose the best tools available to make the comparison meaningful. Part 1: We calculated a new muzzle velocity, 4.6 ± 0.2. Part 2: We use the muzzle and angle to calculate the uncertainty of the horizontal distance. • Dominant Source of Uncertainty (2 points) Identify and discuss the dominant source of uncertainty in your result. Use error propagation calculations (as appropriate) to support your explanation. • Connection to Physics (2 points) Demonstrate how the relevant physics equations are connected to your analysis plots and are used to obtain your presented result. 6 Last weeks velocity was 4.71 m/s Using this formula, R should be 2.26m

Recalculated with R= 2.17m, so then v0= 4.61 m/s Part 2: vertical distance is .28 m, y distance is 2.17m
