2. Relevant equations

Vy^{2}= Vyo^{2}+ 2a_{y}t

y = 1/2(Vyo + Vy)t

3. The attempt at a solution

So I have "solved" this problem with both the equations above.

Using the Vy^{2}equation I get the result of 32.83m/s.

Using the other equation I get a result of zero, because Δy = (0 - 55) = -55. However, if I consider that 55m a positive value, then I get 32.83m/s... same as first equation.

I knew Vyo = 0m/s because the initial velocity would only be in the x-direction since the ball "is thrown horizontally". To prove it I did the equation Δy = Vyot + 1/2a_{y}t and got a result of 0m/s.

So, where am I going wrong?

I actually have a much bigger problem than just this one I'm posting. For some reason I cannot wrap my head around physics problems. I can do calculus, logic classes, philosophy, etc, but for some reason cannot make my mind look at physic's problems in the right way. Conceptually, all of these kinematic questions seem easy, but I am spending WAY more time on these problems than should be necessary. If you have an answer for this conundrum I welcome your responses...
