Mechanics 2020 Pearson Edexcel A level maths 

I don't even do a level maths anymore but that start with the inverse tan alpha was just hilarious

Typically, if you want to replace a whole word or in your case a letter for question 4's working in this paper, you can use the find and replace function in microsoft.

I saw an interesting question in an old textbook similar to Q5. It simply said that a projectile is launched from a height h with a velocity u, show that the maximum range is: u/g sqrt(u^2+2gh). Give it a go it can be done a few ways.

In the projectiles question if you use the equation for the motion of a parabola which is in this case, because it is launched from a height, y=25+ xtanalpha-gx^2(1+tan^2alpha)/2U^2. With alpha being 45 in this case, so tan alpha is 1, makes the maths a lot easier.

I think "r" is Position vector whereas "s" is displacement. r=initial displacement from origin + Displacement iirc

This paper was easier than a triple double against the warriors

the goaaatttt

Thanks

Will you do the mock set papers a well for further maths.

Are you not going to do stats papers and can you do FM2 papers please?

Will u do decision maths or further stats papers?
