Homework Help: Writing Parametric Equations

  1. Dec 14, 2009 #1
    1. The problem statement, all variables and given/known data
    Given:H0-1.6, time in air - 3.02 s, horizontal distance thrown - 10m
    Solve:V0 and write parametric equations for x(t) and y(t) - the horizontal and vertical positions of the ball

    2. Relevant equations

    3. The attempt at a solution
    for V0 I got 14.268
    when trying to write y(t) I got y(t)=-4.9t^2+14.268t+1.6

    I need help verifying that what I got is correct, if any additional information is needed write. I also need help writing x(t), the horizontal position of the ball equation

    How did you get 14.268 for V0?

    For writing x(t), what is true about the velocity component in the x direction?
