Constants

Assuming the ball's initial velocity was $55$ above the horizontal and ignoring air resistance, what did the initial speed of the ball need to be to produce such a home run if the ball was hit at a point $0\mathrm{.}9m(3\mathrm{.}0ft)$ above ground level? Assume that the ground was perfectly flat.
