    • @PhysicsclassroomVideos
      @PhysicsclassroomVideos  ปีที่แล้ว

      Nope.
      (m^2/s^2)÷(m/s^2) = m
      Note the additional ^2 in the numerator ... which might be what you meant.

    Bruh, I tried solving this without a calculator. My brain died after getting this far before realizing I have to go to bed and that calculating this many things including exponents and division was simply to much right now, Great video, I understood all the concepts without ever taking algebra physics or anything, when I told my school I liked math they put me in the most boring low level math classes because they give the better classes only to kids who went through middle school math.
    Obviously I dropped out of that garbage.
    Anyway I got this far without a calculator before deciding it's time to relax and go to bed.
    D = Vo * T + 1/2 * A * T^2
    D - (0 * 3.80s) + (1/2 * 6.52m/s * 3.80^2)
    D= 0, ((1/2)6.52= 3.26)) 3.80^2
    D= 0, 3.26 3.80 * 3.80 = 380x380/100....
    380x380= 380x380/3 =
    8/3= 2.666, 2.666x3=8 true
    126.666x126.666
    126.666x126.666
    26.666^26.666=400 +x
    X= (6.666*26.666) 20x6.666= 66.666+66.666 = 133.222222...
    There's a lot more I have yet to calculate. without a proper background in mathematics the steps to simplify these problems are quite a lot.
    To You tube trolls, No I didn't reach the answer yet so don't reply some thing about how I didn't get it right when I didn't even finish the equation. Yes I know the answer already, because I watched the video, Knowing the answer won't help me solve the problem tho.

    • @yamiomo3277
      @yamiomo3277 3 ปีที่แล้ว

      I am realizing more and more how spoiled we are to have calculators and smartphones, Everyone used to do ALL the math's by hand. I thought it would be handy to try learning the basics without help of technology, Then I realize I would be obsolete in most situations doing mathematics by hand when we have algorithms and calculators to solve these problems for us. In some situations, doing the math by hand is the only way, but In those situations Best leave it to an expert in the subject.
      I admit an expert would probably use the tools available to simplify the parts of the problem that they could to save time.
      Even still, Maths is hard. and anyone who says otherwise hasn't tried putting down the goddamn calculator.
