- For each graph, make a table with the following (x, y) coordinates: (a) initial position, (b) furthest point of recoil, (c) approximate point of release, (d) apex of trajectory, (e) end of trajectory. Mark points (b) and (c) with a horizontal line on the graphs, for visual reference.
- Calculate the following and add them to the table: (a) horizontal length of active throw, (b) horizontal length of trajectory, (c) vertical height of trajectory to apex, (d) vertical height of trajectory from apex to ground, (e) time of trajectory from release to ground, (f) average horizontal speed of the throw, (g) average vertical speed of the throw, (h) average horizontal speed of the trajectory.
- Which throw involves a faster horizontal speed of throw?
- Which throw results in a higher apex of trajectory, as measured from point of release? As measured from apex to end point?
- Which throw is more successful? Why?
- Why does the red line go down in the first graph, and up in the second graph?
- Redraw the graphs so that the approximate furthest point of recoil begins at (0,0), and both throws are in the same direction, from left to right.
