AP Physics B question

<p>Show that on a roller coaster with a circular vertical loop , the difference in your apparent weight at the top of the circular loop and the bottom of the circular loop is 6 g's-that is, six times your weight. Ignore friction. Show also that s long as your speed is above the minimum needed, this answer doesnt depend on the size of the loop or how fast you go through it.</p>

<p>Bump, anybody? ...I need to hand this in tommorow..</p>

<p>post your solution and i'll check to see if it's correct. we're not going to do the whole thing for you.</p>

<p>Thing is , I dont get the question (btw this it not a whole assingment if thats wat ur thinking lol, its just a q out of a worksheet thing or w.e) Like it doesnt really make Any sense..at least give me hints /pointers..
PS:I m not being lazy or anything, I Just Dont get it
Thx in advance :)</p>

<p>apparent weight is the weight that the person feels he or she is. it is the sum of all the vertical forces acting on the person. </p>

<p>that should be sufficient, everything is self-explanatory.</p>

<p>Ok i THINK i got it haha, I might post up my answer later.. heh..</p>

<p>Btw some question askes this "assuming the body is 15% effcient, what rate of energy input was required."</p>

<p>wats that supposed to mean exactly? and how do u do that?</p>
