Solving for t in Physics Problem: y=0

[lespommes]

Homework Statement

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

Homework Equations

V = Initial Velocity
g = Gravity
t = Time

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 don't have some extra info, it looks impossible to solve for t. But, you might have as the initial velocity v=0, which of course makes it easy to solve for t. What is the exact problem, or is what you already wrote all?
