Good ol' angry birds :') u_y = vsin60=\frac{\sqrt{3}}{2}v u_x = vcos60 = \frac{1}{2}v \Delta x = u_x t 45 = \frac{1}{2}vt \Delta y = u_y t + \frac{1}{2}a_yt^2 34 = \frac{\sqrt{3}}{2}vt - 4.9t^2 34 = 45\sqrt{3}-4.9t^2 t = \sqrt{\frac{45\sqrt{3}-34}{4.9} \approx 2.99 v = \frac{90}{t} =...

Re: HSC 2013 4U Marathon I don't think it's a contradiction, i just made a mistake in the 5th line so i technically didn't prove the left side of the inequality :(

Re: HSC 2013 4U Marathon Consider \lim_{k \rightarrow \infty} \int ^k_0 \frac{1}{1+x^2}dx. If we draw out the graph of y=\frac{1}{1+x^2} and then draw out the lower rectangles of breadth 1 unit, we can determine that \sum _{k=1} ^{\infty} \frac{1}{1+k^2} < \lim_{k \rightarrow \infty} \int ^k...

Weis Mango & ice cream ftw So, when & where shall i meet you guys?

Always look at the previous part as its most likely used. Rearrange part (a) as i notice how they look pretty similar and i'm going to let x = cos\theta 4x^3-3x-cos3\theta = 0 Compare this to (b) and you notice how they're pretty similar. If you let cos3\theta = -\frac{1}{2} and multiply...

I've heard good things about In2Physics. That's just a list of heaps of textbooks, not necessarily suggestions..

Re: 2013 HSC physics marathon What about landing? Pretty good answer overall :)

re: HSC Chemistry Marathon Archive Good attempt, but you should be focusing more on the bonds. Also, it asks for "structural formulas" 1-butene has a carbon-carbon double bond whereas butane only has carbon-carbon single bonds. Double bonds are much more reactive than single bonds...

Prolonged procrastination led to a feeling of guilt that drove me through short bursts of intense study periods This is what I did that worked for me, but knowing what you're aiming for is better imo.

One way of doing this would be to draw it out (by ruler + protractor) accurately using a scale then measuring the net force from that.

re: HSC Chemistry Marathon Archive Explain the different reactivity of butane and 1-butene with aqueous bromine, illustrating your answer with a chemical equation using structural formulas. (2 marks)

re: HSC Chemistry Marathon Archive Very close but not quite. Reread what you typed and you'll probably figure it out.

re: HSC Chemistry Marathon Archive Yep

Re: Instant Noodles: Do you drink the soup? I sometimes do this haha

re: HSC Chemistry Marathon Archive Nope, good try though :P Perhaps move further in to the HSC chemistry course and then reattempt this question.

Re: Production of LDPE & HDPE clarification Those equations are suitable for the production of LDPE. Initiators react and become apart of the products. Catalysts can react but they don't end up in the products. I don't think i've seen a clear cut explanation of how the production of...
