Edexcel IAL Physics Unit 1 14 May 2019

Hey can you pls help me solve 14 (c)?
Paper- 2018 May Phyics unit 2 (old syllabus)

Hello, how is your preparation?

My preparation is pretty good, just need to revise and do latest papers of 2018 and 2019.

Any tips for resolving vectors like the last few q.s in the 2019 jan unit 1 new spec paper

And any ideas on how to revise ive already done past papers topicals and textbook

How many marks minimum out of 80 put u in the safe range for an A ive taken private tuitions with me as the only student so i have no idea how much marks im supposed to be getting at this point

Just don't even think about the possibilty of minimum marks cuz this will make you lazy, Make your goals higher and you'll achieve higher. When I started doing past papers, I was getting about 50-60/80 and after so much practice now I get more than 70. Make your own list of problem questions from past papers, in which you struggle cuz they are your weak points.

I have not done that paper yet, but resolving vectors is usually easy. All you need is to apply the tip to tail rule, and keep practicing.

Go to physicsmathstutor.com And then go in edexcel physics section, then there are topical questions. If your weak point is vectors, you can practice it there

You can use n= 1/sin C and rearrange it to c =sin^-1 (1/n), n is given in first part, so c = sin^-1 (1/1.31) =49.8°

Anyone here doing A2 (unit 4,5,6)?
