Crouchie's Lawyer Posted 30 October, 2008 Share Posted 30 October, 2008 The traffic has cheered me up no end It took me 30 minutes to get from Hyde Street in Winch to the M3 (through the one way system) last night. I was not happy Link to comment Share on other sites More sharing options...

Crouchie's Lawyer Posted 30 October, 2008 Share Posted 30 October, 2008 I wish I was a kid again. Knowing what I know now, I would have so much fun with exam test papers like the one above. Just trying to write funny sh*t to make the teachers laugh. Infact, that would be a wicked idea for a book, a load of exam questions which have been made into jokes! Im trade marking that you f*ckers! Link to comment Share on other sites More sharing options...
saint_stevo Posted 30 October, 2008 Share Posted 30 October, 2008 it took me 2hrs 20 to get from hedge end to Eastleigh thru Fair Oak. I wish i was a kid again too, i would jump off northam bridge and save myself 70odd yrs of misery Link to comment Share on other sites More sharing options...

Things cant be that bad, just think, the time you were in traffic was time you were not at work. Every cloud and all that. Link to comment Share on other sites More sharing options...

bungle Posted 30 October, 2008 Share Posted 30 October, 2008 Part (b): Once an item has come to rest, it is therefore not moving. As the question does not indicate any further forces being appplied to the object, surely therefore it is impossibe for it to move after it has come to rest? Therefore, it seems a silly question. Although, I suppose this is a bit of a moot point considering the elephant. Link to comment Share on other sites More sharing options...

Although, I suppose this is a bit of a moot point considering the elephant. Not so, Bungle, my good man. As you can see, it will come to rest for just a split second as it changes direction, 180 degrees. The split second it stop travelling forward, it will be at rest, until the spring then recoils and exerts energy upon the weight to make it move in the opposite direction, I think.

I believe that the question is poorly worded. In my book the phrase "comes to rest" would mean it has stopped. Link to comment Share on other sites More sharing options...
Crouchie's Lawyer Posted 30 October, 2008 Share Posted 30 October, 2008 I believe that the question is poorly worded. In my book the phrase "comes to rest" would mean it has stopped. Technically it does, the spring just moves it again Link to comment Share on other sites More sharing options...
bungle Posted 30 October, 2008 Share Posted 30 October, 2008 (edited) Technically it does, the spring just moves it again I can only remember F = ma. But I do not know how to convert this into distance travelled. We know F = 100, m= 3 and a = 9.8 m/s/s x 5. Beyond that I am stumped. Edit: The above is possibly a load of crap and not helpful.

You have fallen into the same trap as me. Technically it will come to rest before changing direction again due to gravitational force. Link to comment Share on other sites More sharing options...

Technically it will come to rest before changing direction again due to gravitational force. Well yes, but what I mean is it is badly written on two fronts. I hate all involved with that question.

bungle Posted 30 October, 2008 Share Posted 30 October, 2008 Well yes, but what I mean is it is badly written on two fronts. I hate all involved with that question. Don't hate on the elephant. I wish I had some idea as to how to answer the question. Clearly one just needs to know the appropriate formula (and also that acceleration due to gravity is 9.8 m/s/s).

I have tried this, but as I don't know the name of the required formula it is not easy to find the exact formula we require. The one in the initital workings can't be far off, but even that hasn't helped! Edited 30 October, 2008 by bungle I cannot do the typing Link to comment Share on other sites More sharing options...
Hatch Posted 30 October, 2008 Share Posted 30 October, 2008 The question doesn't state that the spring is fixed, therefore the 3-Kg object might just smash it out of the way. Link to comment Share on other sites More sharing options...

I dunno, clearly the elephant couldn't get past it, so it must be quite strong. Link to comment Share on other sites More sharing options...

Hatch Posted 30 October, 2008 Share Posted 30 October, 2008 and anyway, the examinee has got it all wrong. To answer question a, he needed to circle the 'x' and write 'it's here' next to it. Link to comment Share on other sites More sharing options...
Scudamore Posted 30 October, 2008 Share Posted 30 October, 2008 What, don't you own one? I have two...i thought everyone did...thats why i questioned the use of the singular... I think anyone that would attempt such an experiment would use both ramps...just to spice it up... Link to comment Share on other sites More sharing options...

Scudamore Posted 30 October, 2008 Share Posted 30 October, 2008 Will there by acceleration due to gravity, or is she on top? She lies down in a tight fitting top in a cold room...the elephant is lured in in the belief that she is smuggling peanuts... A honeytrap of the highest order...

Weston Super Saint Posted 30 October, 2008 Share Posted 30 October, 2008 Has the examiner underlined the word elephant because the pupil appears to have made up the word elephart instead? Would the pupil have got full marks if it were not for his inability to spell elephant? Link to comment Share on other sites More sharing options...
