Solve for t

  1. Mar 26, 2009 #1
    1. The problem statement, all variables and given/known data

    I put this under Pre-Calc because we're not doing Physics, we're just solving for t and don't know the algebra for it.

    Solve for t

    y = -4Ve^(-t/4) - 4gt + 4V


    2. Relevant equations

    V = Initial Velocity
    g = Gravity
    t = Time

    3. The attempt at a solution

    y = 0 (Physics problem, hitting a golfball and solving for t when y = 0)

    -4V = -4Ve^(-t/4) - 4gt
    V = Ve^(-t/4) + gt
    1 = e^(-t/4) + gt/V
    0 = -t/4 + ln(gt/V)

    Couldn't get further

    if you dont have some extra info, it looks impossible to solve for t. But, you might have as the initial velocity v=0, wich of course makes it easy to solve for t. What is the exact problem, or is what you already wrote all?
