[URGENT] Edexcel IAL Physics Unit 6 Help

Hey, tomorrow's the unit 6 physics exam, I was doing some past papers and I encountered upon this dilemma.. It's from the paper dated June 2013. My question is that for part 1.d), I've did a completely different method to what the marking scheme says but I think what I've did is correct. Care to check? Thanks a lot. My working is attached above.

QP: https://goo.gl/XWC9aD
MS: https://goo.gl/Kc6x5m

Sorry, I had a mark scheme printed out, and for some reason it didn't get printed on. :frown:

Pretty good i think, the only one i found a bit difficult was question 2, assuming i got the rest correct!
Can we start discussing our answers?

I ain't a pro but I'll tell you some tips :P

-PAST PAPERS
-this website (ask questions if you have a doubt, a handful of people are more than happy to help)
-official edexcel a2 physics book
-edexcel a2 revision guide
-did i mention past papers?

And search up whatever relevant info you can on google (According to the spec), I've seen some stuff that I've never seen in past papers pop up in exams. Just keep studying and you'll be fine :biggrin:
