Consider the 2012 case of the 17 year old unarmed Trayvon Martin who was shot and killed by George Zimmerman who regularly watched for suspicious persons in the Sanford Florida neighborhood where Trayvon lived. Zimmerman was later acquitted of all criminal charges in this killing. Or consider another case that same year of the 47 year old software engineer Michael Dunn who confronted four Black teens about their loud rap music in their SUV at a Florida convenience store. Dunn claimed he felt threatened and fired 10 shots into the SUV killing 17 year old Jordan Davis. Dunn fled the scene but later reported the incident to the police, claiming self-defense. On February 15, 2014, Dunn was convicted of attempted murder against the three surviving teens but the jury could not reach a verdict on the charge of murdering Jordan Davis. He was later retried and sentenced to life without parole for the killing. For this week's discussion on equality and discrimination, please answer just ONE of the following two questions and then post at least two reply postings to others in the discussion: [1] What do you see as the difference between individual racism and systemic racism and which, if any, are at work in the killings of Trayvon Martin or of Jordan Davis? Explain your position. Discuss the case you choose with two different people, preferably at least one of them being a person of color. Do they see racism at work in this case, and, if so, do they see it as individual racism or systemic racism or both?

A ball of radius $r$ and density $\rho$ falls freely under gravity through a distance $h$ before entering water. Velocity of ball does not change even on entering water. If viscosity of water is $\eta$, the value of $h$ is given by (a) $\frac{2}{9}r^2\left(\frac{1-\rho}{\eta}\right)g$ (b) $\frac{2}{81}r^2\left(\frac{\rho-1}{\eta}\right)g$ (c) $\frac{2}{81}r^4\left(\frac{\rho-1}{\eta}\right)^2g$ (d) $\frac{2}{9}r^4\left(\frac{\rho-1}{\eta}\right)^2g$
