- Sanitarium, on 10/12/2007, -5/+368My physics prof can expect to see this on my paper next Monday.
- omgitscolin, on 10/12/2007, -4/+366But genius answer.
- spidoman, on 10/12/2007, -24/+307Funnier: http://cs.uni.edu/~wallingf/blog-images/humor/find-x.jpg And it's a much more intelligent answer.
- gerry87, on 10/12/2007, -4/+265Looks like the elephant's going to get a 3kg object up his ass.
- Fracture98, on 10/12/2007, -0/+189If granddad is asleep in his lazyboy and I throw him and the chair off the balcony he is moving while at rest.
- blizzok, on 10/12/2007, -23/+156ah, but will they blend?
- inactive, on 10/12/2007, -7/+140Holy ***** I haven't laughed this hard in a while.
- inactive, on 10/12/2007, -15/+147Oh come on.
a.
Ke = (1/2)k(x^2)
Pe = mgh
Ke = Pe
(1/2)(100)(x^2) = (3)(9.8)(5)
(x^2)[/50] = (147)/50
x^2 = 2.94
x =~ 1.715
b.
Huh. Does the object continue to move... after it comes to rest.
No. - pjleonhardt, on 10/12/2007, -5/+129if it is frictionless as stated, it will return to its starting position and keep moving between the two forever.
- Ascendant, on 10/12/2007, -5/+127quoth the elephant:
"im on ur curved frictionless ramp, blocking ur objects" - RatherDashing, on 10/12/2007, -5/+126True story:
My friend had a very tricky math problem to which is just drew the best rendition of Robocop he could in the remaining test time. The teacher than awarded him 1/10 points. And this was in college.....tier 1......calculus 3! (damn you green's theorem!) - najdorf, on 10/12/2007, -6/+97Best thing is that he actually did solve the problem (the 2 equations are right and trivial to solve), the teacher didn't get it though ;)
- Silby, on 10/12/2007, -3/+91If only that worked for Honors Chemistry too....
"The two compounds cannot react. There is an elephant in the way" - debuggercll, on 10/12/2007, -0/+88It couldn't, there's an elephant in the way.
- pagit, on 10/12/2007, -1/+77I put "God only knows" for an answer on a physics exam.
The instructor gave me 1/3 for the mark for that question and wrote, "god only knows if you will pass this year" - WaterDragon, on 10/12/2007, -0/+76The student drew an elephant.
Then the teacher reciprocated by circling the elephant and drawing a donut.
a. What was the teacher trying to say?
b. What kind of donut was it?
c. Will the elephant eat the donut? - hobbers, on 10/12/2007, -0/+72Yep, it will return to a height of 5 m since no energy has been lost in the system. It just keeps being exchanged between potential energy (both in the height and spring compression) and kinetic energy.
Frictionless surfaces, gotta love em. They make physics so easy. - Scik, on 10/12/2007, -4/+73Hilarious! I would have given them the point for making me laugh...
- timo1023, on 10/12/2007, -4/+63If I could digg this 50 times, I would... pure original humor.
- elnerdo, on 10/12/2007, -2/+58No, he got an "O" for OUTSTANDING!
- sirloin, on 10/12/2007, -0/+55The truely dificult question is the zen like question 2b
"Does the object continue to move after it has come to rest?" - najdorf, on 10/12/2007, -0/+48The guy actually knew how to solve the problem: he wrote the gravitational potential energy at the beginning of the system, the potential energy of the spring at a generic compression x, now he just needs to equate the two to find x. (50x^2=147.15)
- linksdeity, on 10/12/2007, -4/+47I had a similar experience in my English class.

Yeah, yeah, i know i misspelled some words, I'm dyslexic :p - Akaji, on 10/12/2007, -4/+43Part b of the question is phrased poorly. By 'rest', it simply means a moment in time in which the object is not moving. Since the spring is compressed, it will exert a force on the object, very possibly making it move back the way it came. I suck at the whole math part of physics, so I have no clue how far it'll move...
- the_penguin_boy, on 10/12/2007, -0/+38A friend of mine once put Chuck Norris as an answer to a history exam question he didn't know the answer to. The teacher gave the entire class an A.
I want a teacher like that. - OutrightLie, on 10/12/2007, -1/+34My Civilization professor has something called the pathetic clause. We have these "5 point IDs" on each test where you have to name the who, what, where, where and why of the person or place listed. If you don't know the answer, and can write down something so pathetic or humorous it makes him laugh, he will give you 1 or 2 points.
- EasY_TargeT, on 10/12/2007, -4/+33i wish i knew this yesterday, dam physics exam.
- floridiot2, on 10/12/2007, -0/+29It's not the meaning of life, it's the answer to life, the universe, and everything.
- Grumps, on 10/12/2007, -0/+26That makes sense.
- scuzzman, on 10/12/2007, -1/+26@blizzok
That's the first time I have ever dugg a comment with "but will it blend" (or a variant thereof) in it. Well played indeed. - rm999, on 10/12/2007, -2/+25maybe they crossbred an elephant with a potbellied pig.
- kewobrian, on 10/12/2007, -1/+23Instructor is an ass. Student had the biggest part down, the two equations. All the student needs to do is solve for x. I would have given 7/10 and +1 for being creative.
- theratster, on 10/12/2007, -0/+21the teacher must have been a fan... otherwise (s)he wouldn't have got the joke.
- cvh™, on 10/12/2007, -6/+26@andyrobo60
You couldn't find x? Its close to the spring, under the arrows by the dotted lines. - Rikushix, on 10/12/2007, -3/+22Was question 8 "what is the meaning of life?"
- soogy, on 10/12/2007, -0/+19@xister
At -273.15°C.
/smart ass answer - thehouse, on 10/12/2007, -1/+20but pig and elephant genes won't splice!
- EasY_TargeT, on 10/12/2007, -3/+22you mean the elephant neutralizes the reaction therefore its not possible.
- ButchyFuego, on 10/12/2007, -0/+18I like the question mark next to the elephant, I wonder what the teacher was thinking
- crashflow, on 10/12/2007, -0/+18i bet its somewhere along the lines of "WTF?"
- juxtapose, on 10/12/2007, -1/+18I thought the giraffe was in the way.
http://blog.igorfoox.com/2006/12/14/how-do-you-put-a-giraffe-into-a-refrigerator/ - ziki, on 10/12/2007, -1/+17a. a donut is disallowing me to grade this?
b. looks like a vanilla glazed
c. it may take a while - tylerni7, on 10/12/2007, -0/+15@netdriod
The object gains energy from gravity as it falls down the ramp, it compresses the spring and (with a perfect spring, as is the case in this problem) the spring will then exert the same amount of energy that it was pushed with. Since there is no friction, this energy will be the exact same amount of energy that the object gained when falling down the ramp, and therefore it will go back up to the original height. - Ibox, on 10/12/2007, -2/+17So your teacher wasn't a fan of The hitch hikers guide?
- inactive, on 10/12/2007, -0/+14I'm not saying i have all the answers, but I do have all the answer keys
- analogengineer, on 10/12/2007, -3/+17re: rm999..."maybe they crossbred an elephant with a potbellied pig."
Then you'd get elephant pig sin (Θ) - Mac2492, on 10/12/2007, -1/+14You could put an elephant, then say "truncate the answer".
- davidrools, on 10/12/2007, -0/+12and idealized springs (that don't convert any energy to heat when compressed/uncompressed)
- obijohn, on 10/12/2007, -0/+11@Fantom: Can you really be a 32-yr-old geek with a hot wife and successful business in Australia? No, there is an elephant in the way.
- joltjake, on 10/12/2007, -0/+11lmao, +3 for creativity.
