4 paragraphs is ideal prescribed, related, prescribed, related. That way you get a nice natural comparison and contrast without really having to artificially incorporate it

Believe it or not memorising a whole essay is far easier

http://prntscr.com/ke7p6k Apologies for format- my LaTex is still to slow to use here.

http://prntscr.com/kcrsrn Thanks

This is an insane point of view. In the long term I think the impact on physical/emotion/mental wellbeing will be quite the opposite.

http://prntscr.com/kc3cpc I get that you apply the chain rule twice, and use arc length of circle on the winch, but can't get seem to get the second component of that rule. Also how would you do part iv. In this- http://prntscr.com/kc3pn0 Thanks in advance

http://prntscr.com/kabai3 Thanks

Yes but for some values won’t the ball fly over the net ? Because the net doesn’t exceed the maximum height

http://prntscr.com/k9ehx7 Part iii. And any tips for these inequality style projectile questions? I'm not great at them. Thanks

Yes and No. Depends on what you are asking. It's their [Nesa's] thesis for this particular paper, which means it shouldn't be yours. They are asking you to respond to the ideas which they have put forward in that statement. A sophisticated response would take their idea and apply into a...

http://prntscr.com/k8nyt2 For part v I can find the first set of restrictions i.e. $ 15 \leq \theta \leq 45 . But then the other solution to the quadratic is 71.33... how to I find the upper limit? Thanks

A particle is moving in SHM in a straight line. It’s max speed is 2m/s and it’s max acceleration is 6m/s^2. Find the amplitude and the period of the motion. Also in $ $v^2=n^2(a^2-(x-c)^2)$ $ is $ c always the centre of motion? Thanks

I tend to just read over my notes heaps. I feel like knowing and understanding content is far more important than attempting a past paper that you have no clue about. Even though it feels unproductive it’s better to read over notes than just complete endless past papers. It's true past papers...

Polynomials is an Extension 1 topic anyway.

A particle moves in SHM with acceleration given by x^(..)=-6x ms^2. When x=2, v=+-4. a. Find the period b. The amplitude c. Find the maximum velocity and acceleration Thanks in advance

Is there an online version of Terry Lee or Fitzpatrick? Or where can I buy them?

Has your school finished the internal assessment regime already?

Basically yes we derive the equations for the motion of the ball once it has hit the advertising hoarding. 1. Set up the vector resolution (the right-angled triangle) for after the ball hits the sign with the information given in the question, i.e. V= 0.2(5√58). α = tan−1 (2/5). 2. Work out...

When do they start?

Does anyone know any other decent 3U textbooks with harder style questions apart from Cambridge? If so where can I get it?
