    How was maths p62?

    inclusive means we dnt have to aproximate n its in aproximation that we add or minus 0.5 rite inclusive means including 38 n 41 tht means rite away p less than exact 38 subracted from p less than exact 41

    How was maths p62?

    i do have all the answers noted

    how was M1 42

    well but then the formula for power is differebt ib tht case its P=Fcos0 come on hows it possible to ignore he weight component
  5. D

    how was M1 42

    no mine was not this hehe
  6. D

    how was M1 42

    h how cum? 25.6?
  7. D

    how was M1 42

    well for the third one yea it was for 2 marks i simply applied distance formula v2=u2+2as cs we had distance 216 final velocity 0 a=-0.72 and calculated v
  8. D

    how was M1 42

    well i remember the distance OA was 216m for b part it was like -0.72m/s2 n for third part iam confused

    how was M1 42

    yup i got the same and wht abt last ques last part?

    how was M1 42

    n wht abt last ques last part the one for initial speed?

    how was M1 42

    n was q 4 answer 39N n diection 22.6'AC from x direction ?
  13. D

    how was M1 42

    well iam not repearing i completed my maths in 3 months n have given as paper and as far as my little experience works its impossble to ignore x component of weight cs it was a slope the rest is with the mark scheme
  14. D

    how was M1 42

    w well i dont get it hows this possible like u mean when we were calculating f=ma for driving force we only had to subract 1000N resistance from driving force n equal it to ma?we dont have to subract the x component of weight? n then when we get df then simply power=force x velocity to get velocit?
  15. D

    how was M1 42

    well u r talking abt mayjune 2012 paper? i ignored the weight x component n took friction directly n i dont get it u mean that u had not calculated x component of weight separately and got ques rite?
