    Start every projectile motion problem with the Displacement Equation (DE) and the Velocity Equation (VE) for both horizontal and vertical directions. Next modify the equations to reflect your known values - creating a toolbox! Then solve for your unknown quantity. Good luck!

  • @JesseMason
    @JesseMason  11 років тому +54

    Combing textbooks and the internet for an equation specific to your situation is usually a frustratingly fruitless endeavor. Instead, start every projectile motion problem with the Displacement Equation (DE) and the Velocity Equation (VE) for both horizontal and vertical directions. Next modify the equations to reflect your known values - creating a toolbox! Only then will you have the right equations you need to solve your problem.

      To find Yo without having time though, don't you need another equation, V^2 = Vo^2 + 2a(X-Xo)? I think that would be Voy^2 + 2a(Yo) = 0 simplified with your variables

    For peak height, there's an equation I find easier to use in this case: 2ad = V^2 - Vo^2. And it become even easier because V = 0m/s when finding peak height. a = -9.8m/s, d = the peak height. Hope this helps :)

    • @peterwalter2717
      @peterwalter2717 3 роки тому +1

      I was also stumped on this for a while. He adds the S to the left side of the equation because it is a problem where the projectile is launched from a ledge. Therefore we need to add the height of the ledge to the vertical displacement.

    7:22 at the moment of imapact how is the vertical displacement = 0?

    • @hwangyeddeong6293
      @hwangyeddeong6293 5 років тому

      Because at impact, the projectile is already landed at land which is at the x-axis, wherein the y is 0. Correct me if I misunderstood the question.

    • @Baykonn
      @Baykonn 5 років тому +2

      @Dave Henning Yes, the displacement is -100m, but because of where we set the origin of our x,y plane, it's position would be indicated as 0m. Remember that it started at 100m.

    It's not "v sub oh" it's "v sub zero" or "v naught". But other than that, this is a great demonstration of solving a kinematics problem, and the problem solving process in general.

      i still don't understand why the acceleration become positive because acceleration in earth in always negative g, or is it?

    • @kastieldj
      @kastieldj 6 років тому

      Depends on the direction of motion I think. If you are moving away from the centre of the earth (up) gravity is not helping you. Whereas, if you are moving towards the centre of the earth (down) gravity aids you. Also depends on how you set the directions, which you should do for every physics problem.

    • @Peter_1986
      @Peter_1986 9 років тому +4

      +sourav ghosh
      You can just set the initial height to zero, and proceed from there.

    • @AlchemistOfNirnroot
      @AlchemistOfNirnroot 8 років тому

      +Sourav Ghosh Pretty much the same thing. List all the horizontal and vertical competent information listed downward, SUVAT. Some information is already known, horizontal acceleration is zero whilst vertical is -g (given that 'up' is taken as positive). Also, at the maximum height final velocity is zero (or initial if considering the right hand side). Then select the correct equation with the variables you know and one unknown. Give me a example question if you want.

    Thanks buddy for deriving all the equations needed to solve that problem. People dont break it down and just toss equations at you and our FE handbook just give the basic equations so I need to understand the where its derived from to solve for each variable. I am studying for my FE (Fundamentals of Engineering Exam) and this was the most helpful video yet.
