## Homework Statement

You're the new home run hitter for a baseball team. Your job is to hit the ball over a fence D away and H high. For a given angle θ calculate the speed with which the ball must be hit v

_{0}to go over the top of the fence.

## Homework Equations

1. y = y

_{0}+(v

_{0}*sinθ)-½gt

^{2}

2. x = v

_{0}*t*cosθ

## The Attempt at a Solution

I tried using H as my y value from eq. 1 and D as my x value in eq. 2. I solved for v

_{0}in eq. 2 (D/(t*cosθ)), then attempted to eliminate t by solving for it in equation 1 using the quadratic formula. Then I substituted the result into the D/(t*cosθ) equation.

The result is a very bulky equation that I'm unsure is correct. A tutor said my reasoning was sound, and was unable to come up with a more simplified answer himself. What do you guys think? Am I even on the right track here?
