Obv. this teacher doesn't know what an elephant is.
-
elephant ftw
-
"(b) Does the object continue to move after it comes to rest?" - ummmm no.
-
The kid is clearly smarter than the teacher. There isn't a correct way to answer that question, unless we live in imagination land where an object can move against another one without creating any friction whatsoever and objects can also contine to move after coming to a rest.........might as well draw an elephant......
-
Well, there is an elephant in the way, so... pow.
-
No. There is an elephant in the way!
-
That's a 100% in my book.
-
the kid knows the answer... he is just being smart... his equations are correct...
-
I think I probably would've commented on the whole "frictionless ramp" thing. But that's just me.

i love this. we had a sub today in bio class and we finished our labs. the guys started pulling out laptops and were playing dota (they blocked the firewall and knew admin password. i dont know how). afterwards they were done and theyre like hey lets look at funnyexam.com. we came, we saw, we laughed hysterically
-
looks like the elephant is gonna get smashed by the 3kg-object.. ;D poor elephant.. RIP! :'(
-
on a "frictionless ramp" (assuming there is no elephant) the object will just be launched back off the ramp and not com to rest until it hits the ground on the other side. For it to come to rest on the ramp, there would have to be friction

ಠ_ಠ

xDDDD pwnzome elephant. A+
-
how can something continue to move after it comes to rest?
-
WRONG! The elephant is not on a skateboard! *ba dum tss*
-
This is relevant to elephants, so it is not irrelephant
-
WTF!?! the work should at least count as some part of a grade right...? I mean... don't we all have to show it?
-
ahahaha
-
I LOVE THIS ANSWER XD!
-
classic
-
hahahaha. thats not an elephant thats a mouse! hahaha, real funny though.
-
wow i know whose this is :)
-
That question is scientifically flawed. The elephant IS in the way. Kudos to the kid!

-
At all the retards commenting on the frictionless ramp. Unless you're trolling (in which case you aren't a retard), this is theoretical physics. Anyone with half a brain knows that a frictionless ramp doesn't exist.
-
ಠ_ಠ
-
in response to this ===> "(b) Does the object continue to move after it comes to rest?" - ummmm no. I must say, who ever said that is totally retarded. the oject wil rest for a small glimps of time then be shot back up the ramp by the spring...... dear God who ever said that is dumb
-
That was a stupid answer. The kid was doing everything just right. Ug = mgh = (3.00kg)(9.81m/s^2)(5m) = 147J Us = .5kx^2 = .5(100N/m)x^2 By the Work-Energy Theorem: Ei = Ef Ug = Us mgh = .5kx^2 x = sqrt(2mgh/k) x = sqrt[2(3.00kg)(9.81m/s^2)(5m)/(100N/m)] x = sqrt(2.943m^2) x = 1.72m
-
This is a much more complicated question that it appears to be. Gravity, slope, spring (oh god). Should have added friction into the equation and just made it the only question.
-
someone get that elephant out of v way
-
Oh god, I literally LOL'd.
-
E P I C F A I L U R E

QUOTE: <> Sure it does dumbass that's what happens when you push something against a spring.">> umm ur the dumbass? after all, the definition of something coming to rest is that it stops moving....and even if u say that thats not it, look at the second part of that question. they r apparently using 2 different definitions for "coming to rest"....fail test!
-
look out elephant!...its coming to spank you!!
-
If I had points to spare, I would totally do this
-
Hehe the teacher drew a boob :P
-
Holy shit. I know this kid :D I was in his class. I lol'd so hard when I saw his test back.
-
mmm that donut the teacher drew looks delish.
-
That problem is so easy. All you have to do is set 1/2kx^2 equal to mgh and solve for x.
-
That problem is pretty easy. You just have to set 1/2kx^2 equal to mgh and solve for x.
-
The teacher made it Super elephant ball
-
Dude most people draw a 0 and O the same. How many f**king ways are there to draw a zero and a circle?
-
its fake. Look at the 0 then look at the O in no. similar?
-
i found x! "... x"
-
Elaphant=FTW
-
Um, if it moved up the slope after coming to "rest" it wouldn't have been at rest, and how could it stop and come to "rest" again midway back up the slope. Can the person who drew the elephant give the teacher a FAIL? Actually, I think he/she did in the only way that makes sense.
-
hahahaha i did this
-
It's on a slope... By coming to rest the professor is asking if it will stop on the slope completely. Since it's on a slope, it would need to come to rest before it continued back down the slope. Therefore (b) is stated correctly.
-
Dambo? Is it really you?
-
hahahahahahahahahahahahahahahahahahahahahahahahaha ROFLLMAOLOL

"The kid is clearly smarter than the teacher. There isn't a correct way to answer that question, unless we live in imagination land where an object can move against another one without creating any friction whatsoever and objects can also contine to move after coming to a rest.........might as well draw an elephant......" Its called physics. sometimes in questions they 'neglect' air resistance, friction etc.
-
whats bad he drew a fantastic elephant and there is a good looking donut in the corner
-
All hail the mighty elefant, dickheads!
-
this are really nice
