Nooo physics is awesome!

Also you shouldn't remove threads once the question has been answered. It'll help other people if they come across it and have a similar problem.

I have done shit all since the HSC, now ready to get to uni and start my course.

Q5 a) $There are 2 forces acting on the system, the tension in the string and gravity. The force from the gravity, using $g = 10ms^{-2}$ is $ \\\\ F=ma \\\\ = 5kg \times 10ms^{-2} \\\\ = 50N $Now, the other mass is resisting the acceleration by gravity, and adding more mass to the system. The...

Go through the syllabus and see what you can remember and what you can't. You should use all the resources you can. It'll help make sure you haven't missed anything.

Re: 2012 HSC MX2 Marathon Yeah you're picky :p. I like that method, it is generally a lot easier ha :D

Well there are 2 forces acting on the system, the tension in the string and gravity. The acceleration is going to be <10ms^-2 as the tension is supplying a resisting force.

The maths in HSC physics is really easy. Doing 2U maths is more then enough to understand it all. All you really need to know how to do is rearrange formula's.

Yeah it was a bit. But still, if you are going to base your belief in something off your feelings, which contradicts all the evidence (and in the case for evolution there is a huge amount) then, well, yeah...

Lol i must have missed this. It's always a good idea to base everything on your feelings... ...

I would just like to know. Why don't you believe evolution to be true?

That brings back unwanted memories..

Q10 $The total distance traveled $=$ the area under the graph. We can split the graph into a rectangle and a square.$ $Area of rectangle $10ms^{-1} \times 30s = 300m $Area of triangle $\frac{1}{2}10ms^{-1} \times 10s = 50m \therefore $ total distance traveled $ = 350m Q11...

Re: 2012 HSC MX1 Marathon This thread reminds me of how little I remember from ext 1...

But why does life need a purpose? Where we are going? Through time? Not sure what you mean by this. Also, I have a question for you, you don't have to answer if you don't want, but I'd like to know. Do you believe evolution to be true and how old do you believe the Earth is?

I don't think it matters. Just so long as they are relativity smart (ie not a complete idiot) then it shouldn't matter.

And what questions are they?

I don't know if that's dumb. Stop the suffering and bring back peace and happiness to all, or keep it going for a while to show them that I am the boss and they need me. I know which one I'd pick. And This basically just enforces what I said earlier. " "According to the devil, God was not...

Because up until a few hundred years ago, it gave an answer to something that had no other answer. Of course, by the time logical, rational though and science came around and was able to explain things without the need of Gods, it was already too big and people are to close minded to give it up...

$It took him 12 years to travel 10Ly's, $\therefore $ he was travelling at $ \frac{5}{6}c $Then, using the time dilation formula, we have $ t = \frac{t'}{\sqrt{1-\frac{v^2}{c^2}}} t' = 12\sqrt{1-\frac{25}{36}} t' = 12\sqrt{\frac{11}{36}} t' = 12 \times \frac{\sqrt{11}}{6} t' = 2\sqrt{11}$...
