answer part A & B!

Problem 9.65 3 21 of 22 Review Constants Periodic Table Part A A typical raindrop is much more massive than a mosquito and falling much faster than a mosquito fies. 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 the mosquito and the raindrop is zero, the mosquito is able to detach itself from the drop and fly away. A hovering mosquito is hit by a raindrop that is 50 times as massive and fasting at 8.9 m/s, a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic? Express your answer with the appropriate units. Value Units Submit Request Answer Part B Because a raindrop is "soft" and deformabile, the colision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the colision? The peak acceleration is roughly twice the value you found, but the mosquito's rigidexoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 109 Express your answer as a multiple of .
