    How can Eldar toss an apple to Rahwa at the top of a steep hill?

    The question ask for velocity and angle... I know how to find the distance from the start to where it drops if they give me velocity and angle. But the question in reverse they give the distance and ask for V and angle. This is my final -4.9*4/Vox^2 + Voy*2/Vox -6 =o and Vox = Vo*CosA Voy...
