Catapult vertical displacement problem

[ama]

Homework Statement

A catapult fires at an angle of 40.02 and has an initial velocity of 5.463. Find the vertical displacement at t=.38 seconds.
I know the following from the problem and logic
vo=5.463
t=.3824
g=9.8
angle=40.02
I calcuated the following
voy=vosin40.02
voy=3.5133

Homework Equations

y=(1/2)(-(g))(t^2)+(voy)(t)

The Attempt at a Solution

I know that the value for voy is valid. I plugged them into this equation and got y=.62696 meters. But it isn't the right answer. What do I do?
