raining cats

I was thinking about what I could do for this journal when I remembered how one of my cats had jumped off the lanai awhile ago. He was trying to catch a bird and although he did get it, he also fell about 21 meters down. He fell straight down so if air resistance is ignored, his acceleration would be -9.8m/s^2. If he started with 0m/s vertical velocity, that would mean his final vertical velocity would be around -20.288m/s. (I found this out with the kinematic equation V^2=InitialV^2 +2ax.) He hit the bush, and considering the rate at which he fell, that was probably way better than him hitting the ground. (His displacement was -21m because he fell down to a lower position than where he started, his acceleration was -9.8m/s^2 because of gravity and the fact that he was speeding up in the negative direction, and his velocity was -20.288m/s because he was going in the negative direction.) He had a major run in with physics, but he survived!
