I need help on my practice lab please help me

Proiectile Lab Choose LAB option. Leave gravity at 9.81 m/sz. Choose any can non ball mass. Part 1 1) Any angle and initial speed re cannon (red button at bottom) 2) Near top right in white bubble click and drag the time/Range/height display box onto each dot for either hahc of the trip. 3) Record data in a data table. Based on decimals provided apply a suitable +/- error to this data. Include t = Os. 4) Using Excel (x-y scatter), plot a height versus time graph and a range versus time graph. (Note: use cumulative 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 fitcu rves/lines. 6) Relate to UM and UAM learned in Grade 11 Kinematics AND to Projectiles learned in Unit 1 of4U Physics. Discuss. (This 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 ofthe cannonball to maximum and set air resistance to maximum. Without re-setting the screen from your rst trial, re the cannon. Sketch on the diagram below, your two cannonball paths. 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 n_ot 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 B 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 grab the answer from the internet!)
