Exercise 4: Discussion
Exercise 4.1 (5 marks)
In the picture below Kari uses a catapult to simultaneously fire treats to Physics Girl and Phi Fox. The treats follow the trajectories shown. Explain how we know that Physics Girl receives her treat before Phi Fox. Please keep your answer to half a page or less and feel free to use words, equations, diagrams or all three, whatever helps you explain the physics.
Helpful hints: 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?).
