QUESTION 1
Imagine that the figure above overlays a series of snapshots, taken at equal time intervals At, from a coconut cannon experiment where a cannon, aimed at a green coconut in a tree, is fired at exactly the same instant as the coconut in the tree drops.
Put on your scientist hat for this first problem, and give us your estimate for the height of the bottom green dot in the dropped-coconut's trajectory. Also, tell us how you got it and what we should figure are the uncertainties in your answer?
QUESTION 2
If this experiment takes place on earth, how long would you expect it to take for a coconut to fall from a height of 10 meters to the height of that bottom green dot, and why?
QUESTION 3
Given your estimate for the total-time elapsed, what do you estimate for the time-elapsed At between adjacent dots in both trajectories, and why?
QUESTION 4
Precisely what do you think happened after the last trajectory dots were recorded, and why?
