Ahh ok so acceleration-wise v is final velocity, thanks!!

v is velocity, a is acceleration, t is time taken, s is displacement, am I right? What does u mean?

What do these formulas mean? I know it's relating constant acceleration but why are there 3 different formulas?

Ohhh it seems I confused myself...... nevermind lol. But if say a question had km instead of m and asked to find the average velocity, do I have to change km to m before plugging the numbers into the formula?

In my lecture notes, it says: All equations use SI units. Convert all values to SI before doing calculations. So don't we convert km to m?

Howcome we don't convert the km to m? The table below metres for length.

Did you find 60m by doing 80 - 20? So they meant last 2 seconds as in the last 2 seconds before 4 seconds? LOL I was thinking the last 2 seconds before reaching 250m.

I know how to find the average velocity for the first 2 seconds and 4 seconds but how do I find the average velocity for the last 2 seconds? Consider a car starting at rest at the beginning of a 250 m street begins to move with constant acceleration. At time t = 2.0 s it is 20 m along the...

Howcome for Practice B you add 180? What's the difference between the two? How do I know whether to add 90 or 180?

It's something about vector direction...

For Practice A, why do you add 90 not 180? How do I know which to add?

Is there a different between magnitude of displacement and displacement? What's the difference other than not giving the direction?

Setting up this thread for questions that I need help with :) For this question ------- A motorist travels 3 km North and 4 km East. What is the displacement from the starting position? Do I just use Pythagoras's Theorem? How about this? A student walks 1.0 kilometer due east and 1.0...

Ask this question after your trials, work hard for your trials so you can improve your ranks.

Taken from the Macquaire Uni website: The benefits of the program include: early offer to selected degree courses that is not based on your ATAR But you should still work hard because you might end up interested in a different course at another university.

Have you memorised everything or know most of the stuff? If yes then do as many past papers as you can which should also fill up the gaps.

good luck bro

Well I recommend you do this: Speak to your Maths teacher to try lessen the amount of homework given, or if that does not work then you need more time to study, and by this I mean studying early in the morning probably around 5:00 for 1-2 hours before you go to school. If you get enough sleep...

If Maths is your strongest then don't spend too much time on it, just do the homework that's set for you if you want to avoid trouble. As for finding balance that will be upto you, anyone will tell you to space out your time so you'll be able to work on what you want to and what not. 4 hours...

- Do you struggle in Maths? Do you really need to be pushed for that subject? Are you lagging behind in that? I feel as if your teacher just cares about you doing well in Maths, which is a bad thing because she's not thinking about your other subjects. It's true, half and hour on each subject...
