Exercise 4: Discussion
Exercise 4.1 (5 marks)
In the picture below Kari uses a catapult to simultaneously fire treats to Physics Girl and Hamlet. The treats follow the trajectories shown. Explain how we know that Physics Girl receives her treat before Hamlet. Please keep your answer to half a page or less and feel free to use words, equations, diagrams, or all three. (Please note that diagrams will be included in the half-page limit.)
Helpful hint: You can use the idea that the x and y directions can be treated separately; they are independent of one another. Ignoring air resistance, we know the acceleration in both directions (what is it?).
