__Correct Answer:__

4.77m/s toward thrower

I get -9.52 m/s which is double and I don't see any mistakes when I double things (I had to assumed symmetry and therefore multiplied by two for when Vfy was 0 so that I can get the full time interval for the horizontal component.

Any help would be greatly appreciated!

Thanks in advance!

Edit: I meant my answer DIVIDED by 2 is correct (not multiplied).
