1. The problem statement, all variables and given/known data

A small block is placed at heighthon a frictionless 30 degree ramp. Upon being released, the block slides down the ramp then falls 1.0 m to the floor. A small hole is located 1.0 m from the end of the ramp. From what heighthshould the block be released in order to land in the hole?

2. Relevant equations

Newton's Laws

Kinematics Equations

3. The attempt at a solution

I did the problem assuming there would be no initial Y-velocity.

And figured out the time it would take for the object to fall to the ground after leaving the ramp, and the X-velocity it would need to get to the whole.

The time was .45 seconds and the X-velocity was 2.21 m/s.

With that it should be really easy to find the time to get to that velocity, and then the height needed to start from....

But I realized there would be an initial velocity in the y direction when it reaches the end of the ramp.I've spent nearly 3 hours trying to solve this problem, and it might be on an upcoming test. I have tried the problem with different axis, and I just can not figure it out. Please help, my test is this week!
