I need help on my practice lab

Part 2 1) Reset the screen by clicking on the eraser icon. 2) Turn off air resistance. Determine the angle and vi needed to land in the target (you could adjust the target as well but not for initial start-up conditions of 80 degrees and 18 m/s). State the two values. 3) Provide calculations that verify your results. (Use given range to find vi and 0 that work in theory and compare to your results from the Sim). 4) Determine the angle needed for maximum range. This could be using the Sim or calculations. You must support your answer (don't just grabChoose LAB option. Leaye grayity at 9.31 mfsz. Choose any cannonball mass. Part 1 1] Any angle and initial speed fire cannon {red button at bottom] 2] Near top right in white bubble click and drag the timej'Hangefheight display box onto each dot for either half of the trip. 3] Record data in a data table. Based on decimals proyided apply a suitable +f error to this data. Include t = (is. 4] Using Excel {xy scatter}, plot a height versus time graph and a range versus time graph. (Note: use cumulatiye height and range add them up as you go!} Include +,:' error bars on Excel! Add a trendline to the graph using Excel. 5] Describe the shapes of the two best fitcurves] lines. 6] Relate to Ul'y'l and UAM learned in Grade 11 Kinematics AND to Projectiles learned in Unit 1 of 4U Physics. Discuss. (T his should be a paragraph long}. Question: Why does it not matter what mass we use for the cannonball? Is it a factor, in real life? What about diameter is it a factor in real life? 1] Increase the diameter of the cannonball to maximum and set air resistance to maximum. Without resetting the screen from your rst trial, fire the cannon. Sketch on the diagram below, your two cannonball paths
