1. The problem statement, all variables and given/known data A baseball is hit at ground level. The ball is observed to reach its maximum height above ground level 3.0 seconds after being hit. And 2.5 seconds after reaching this maximum height, the ball is observed to barely clear a fence that is 320 ft from where it was hit. How high is the fence? (The acceleration of gravity is -32.2 ft/s^2.) 2. Relevant equations Position and velocity vectors and their x and y components [tex] h=(v_o^2 sin^2 \Theta_o)/2g [/tex] [tex] R=(v_o^2 sin^2 \Theta_o)/g [/tex] 3. The attempt at a solution I am thinking that I have to relate the x component with the h equation. I'm not sure how to go about it. I don't know the angle, and it seems as if I don't have enough information in order for me to figure out the initial value of theta.
