    amplitude is also the max distance frm the equilibrium position

    im really confused and is there a diff between x and A and maybe they havle it bcz total dis is 70 of it went 2 times through 35 mm i guess its 1 complete oscillation isn't it?

    ya u hve 2 and 70 mm is the total distance 4 1 complete oscillation look they said total distance so i understood it ths way and also i hve a doubt in wat's the diff between x and A

    the velocity wil be 0.18 ok did u halve the distance

    open ur revision guide 2 page 59 and look at the results plus its written tht the max possible value for sin or cos is always 1

    sry i meant 0.18
  8. S

    Physics Unit 4 JUNE 11/6/12

    the value wil be 0.16

    ok c ths is a tricky 1 1st u hve 2 find angular velocity by using (a=angular velocity x displacement) bt here u hve 2 divide 70 by 2 cuz its the total distance 4 1 complete oscillation then after finding ths angular velocity u use the formula 4 velocity :)

    ok how to find the gradient shld we find whn height is lowest?

    ya i got it nw and the velocity i got as 0.88 by using v=A x angular velocity bt i didn kno y we didn use the sin rule wth it and btw how 2 use the gradient in ths?

    no the 1st part whn they ask abt find amplitude and frequency i cnt find amplitude

    last part of last que and 4 que (4) i got stuck in amplitude
  16. S

    still i didn study astrophysics i didn finish anythng til nw:(im affraid if time won't fit me
  19. S

    Physics Unit 4 JUNE 11/6/12

    ohhh sry t wil nt be zero according 2 the graph i wil do the que again :)
  20. S

    Physics Unit 4 JUNE 11/6/12

    ya i kno tht whn they say max velocity it means displacement is zero hence also time wil be zero at equilibrium position ths wat i kno i don kno if its correct:(
