Problem 9.65 ③ 50t 11 Review I Constants 1 Periodic Table Part A A typical raindrop is much more massive than a mosquito and falling much faster than a mosquito flies. How does a mosquito survive the impact? Recent research has found that the collision of a falling raindrop with a mosquito is a perfectly Inelastic collision. That is, the mosquito is "swept up by the raindrop and ends up traveling along with the raindrop. Once the relative speed between...
