1)Leave gravity at 9.1m/s^2 choose any cornball mass of your choice.2)Use link : https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html3)Then follow steps 1/2/3/4/5/6 4)Then answer the question provided

1) Any angle and initial speed - fire 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 half 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 fit-curves/lines. 6) Relate to UM and UAM learned in Grade 11 Kinematics AND to Projectiles learned in Unit 1 of 4U 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 of the cannonball to maximum and set air resistance to maximum. Without re-setting the screen from your first trial, fire the cannon. Sketch on the diagram below, your two cannonball paths
