“Oh, I forgot to point out that the missing data in the graph is from where the bird went off the screen. This also shows the vertical motion having constant acceleration (because the quadratic equation fits so well). Relating this function to the kinematic equation. The value in front of the t2 term should be 1/2 times the acceleration. This means that the acceleration of the bird (in the vertical direction) is -2 AB/s2. What if this angry bird is actually on Earth? On Earth, the vertical acceleration should be -9.8 m/s2. I can use this to find the length of that sling shot. That is one big ole sling shot, 5 meters tall? Wow. Measuring the red bird, it is almost 70 cm tall. That’s a big bird. Big, angry bird.” - × × ×
