I'm sorry I didn't initially post it, but I did find Δy, which was
Δy = VoyΔt - -4.9m/s^2
I also tried substituting Δx/Δt in place of Vox and Δy/Δt for Voy, but I still could solve for Δt because Δt was always dividing the direction.
Homework Statement
A ball is hit from the ground with an angle of 36 degrees above the horizontal. The ball hits a target 30m ahead and 4m above the ground. Find the initial velocity of the ball.
