<p>I'm suprised that we have yet to start a study thread for the AP that is infamously known to be the most challenging in Collegeboard's arsenal.</p>
<p>Let's ride this **** out together though.;)</p>
<p>Alright let's start this out with...Give a brief outline of Maxwell's Laws and explain why each is significant to the understanding of electromagnetism.</p>
<p>ok seriously, u need to start this out with math from question one lol...i doubt that there is gonna be something asking u to describe a Law on an Engineering Physics test lol</p>
<p>Alright...</p>
<p>A 0.1 kg block is attached to an initially unstretched spring of force constant k=40 newtons per meter vertically. The block is released from rest at time t=0. At what time after release will the block first return to its initial position?</p>
<p>(A) pi/40s
(B) pi/20s
(C) pi/10s
(D) pi/5s
(E) pi/4s</p>
<p>The user who provides the correct solution will get to post the next question for discussion!!!:)</p>
<p>evil<em>asian</em>dictator: is the answer B?</p>
<p>My Solution: define the period of oscillation as (2<em>pi)</em>sqrt(m/k).</p>
<p>I drew a sine curve to help me, the block will drop to a low position of -1 then return past 0 and upto 1, the block will pass point 0 at (1/2) of the period so .157 seconds.</p>
<p>I don't have a question except my 100 page book I printed yesterday of previous AP test/solution answers, maybe evil<em>asian</em>dictator can post another :).</p>
