<p>just to reiterate how hard engineering is…</p>
<p>physics 221, </p>
<p>1200 entered in, mass majority are engineers with AP physics in high school, typically your best and brightest (top 20%) in their high schools, past their initial weed out with relative ease (calc 1, not much of a weed out but it is for a lot of other majors) </p>
<p>800 left by midterms, yep, 1/3 dropped out of the class after taking only 1 exam</p>
<p>final time hits around, those 800 students originally in it that took the exams, over 50% failed it, by that i mean the class average was 58.2%</p>
<p>now, i’m lucky enough to scrape by that class with an A-, but that was no easy task. I remember 2 of the questions that just raped everyone in the test.</p>
<p>“A ladder is a 45 degree angle on the wall with a mass of …, a man stands on the ladder and his weight is …, with no force on the wall wall, the man goes 70% up the wall and the ladder falls, what is coefficient of static friction the floor gives?” all you know is coeff= mu * N, derive how to figure it out</p>
<p>and</p>
<p>“your in a planet ---- in radius with a gravity of ----- at the surface, how much speed is required to escape the planets orbit” (heres the thing, no equation is given to figure it out, you have to derive the speed yourself using potential energy, that also you have to derive, and no, mgh is not potential energy in this case)</p>
<p>what sucks about it too is there is no partial credit, either get it right or get a 0 on that question</p>
