BIO Bacterial motion. A bacterium using its flagellum as propulsion can move through liquids at a rate of 0.003 $\mathrm{m} / \mathrm{s} .$ For a $50 \mu \mathrm{m}-$ long bacterium, that is the equivalent of 60 cell lengths per second. Bacteria of that size have a mass of approximately $1 \times 10^{-12} \mathrm{g}$.The viscous drag on a swimming bacterium is so great that if it stops beating its flagellum it will stop within a distance of 0.01 $\mathrm{nm} .$What is the acceleration that stops the bacterium?A. $1.2 \times 10^{4} \mathrm{m} / \mathrm{s}^{2}$B. $5 \times 10^{5} \mathrm{m} / \mathrm{s}^{2}$C. $6 \times 10^{5} \mathrm{m} / \mathrm{s}^{2}$D. $9 \times 10^{5} \mathrm{m} / \mathrm{s}^{2}$

so really here here to solve an equation of motion and the one to solve is B squared equals initial velocity squared minus two times acceleration times distance X. So this means that acceleration will be b squared minus B not squared over two times x. We know that ends at zero so kind of velocity zero initial velocity is 0.3 meters per second. X is point 01 nano meters. Remember, Nana meter is 10 to the negative nine ah, meters. That's what the man of perfect stands for us. This is 10 to the negative 11 meters or appoint Owen Temps in the late of nine meters rain. So we put all of that in there situational negative point of three meters per second, squared over two times 10 to the negative 11 meters and this works out too negative. 4.5 times 10 to the five meters per second squared. So the answer is Bea, Um, minus five times 10 to the five, because this is just that rounded off to one significant figure
