i love that one, i'd have definitely given them some marks.
also does the question "does the object continue to move after it comes to rest" not strike you as somewhat stupid? by definition, no it doesn't.

are also brilliant. where did you find them?
i think the question means that it's gone down the slope into the spring and they're wanting to know how far back up the slope it will be pushed. badly worded. they should have more questions like ours, with kids sliding down the backs of giant tortoises.
damn. got to get up and go to work. and mark students' work, coincidentally enough.

I was shown the elephant one a little while back and just did a search for other entertaing exam questions =]
They seem to be everywhere if you just do a search for something like "funny exam answers", people usually have a selection.
There are some real cracking ones around the place, it's just tough to find them all in one go =[

WARP DRIVES FTW! i'd do a nice photoshop but i lack for skills and time. i love the fact that the guys who wrote that are from waco...

Although, I thought the idea of travelling faster than the speed of light was theoretically impossible, as time moves slower until you actually start moving backwards =[
Although if you had a "near light speed" drive, time might shift enough to propel the mass actually further, but not faster, than the light would be travelling... So you would get there sooner than the light, but without travelling faster...

it's all about expanding space behind you and contracting it in front of you. so you're moving much slower than light, it's space itself that's shoving you along. a bit like surfing through spacetime.
good stuff.

but by definition something that's moving isn't at rest and something that's at rest isn't moving. (i get your point, it comes to rest but the spring is going to accelerate it back again. it's just a badly-worded question.)

It leads right to misstatements like that[question].
edit: not your more correct one.

We need more questions like:
"An insane tramp takes a snowboard to the top of the tallest hill in town. The hill is a 3:1 gradient and 20m in elevation. Assuming that the road surface is tarmac with a coefficiant of friction as given in Table 1, what speed does the tramp reach at the foot of the hill? How likely is the tramp to survive the collision 10m from the foot of the hill with a ten ton lorry loaded with razor blades? How likely is the tramp to quit halfway down and ask someone for money for a cup of tea?"
