Last minute DESPERATE q's OMFG!!!

<< < (4/4)

Ahmad:
What about it?

Edit: Thinking about it now, I guess it depends on the definition you take as a POI.

avogarbro:
Q21 the projectile is moving up so resistance and weight act down on the object.

Will this exam be difficult and long? I'm scared what happen to methods ppl will happen to us. Who is doing multiple choice first?

brendan:

--- Quote from: "Ahmad" --- f'' to be continuous not f to apply the intermediate value theorem, by virtue of the fact that f'' exists f is continuous.
--- End quote ---


yeah i wud concur with that.

Galelleo:
you should really know all this.


That ski question is a slope, of course its covered in spesh. mass parallel to plane is mgsintheta, and the normal reaction is mgcostheta.


in 22, you take direction as negative because its ascending so you need to change teh value to keep the formulas working.

and its negative g resistance because they say in hte question that its velocity upwards, therefore accelleration is negative.

AkirA:
Yeah, the theorem is proven by observing that f([a,b]) is connected because the image of a connected set under a continuous function is connected, where f([a,b]) denotes the image of the interval [a,b] under the function f. C is between f(a) and f(b) so its in connected set.
