[QUOTE="CapnKrump, post: 5367632, member: 584259"] [h2]Homework Statement [/h2] 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[SUB]0[/SUB] to go over the top of the fence. [h2]Homework Equations[/h2] 1. y = y[SUB]0[/SUB]+(v[SUB]0[/SUB]*sinθ)-½gt[SUP]2[/SUP] 2. x = v[SUB]0[/SUB]*t*cosθ [h2]The Attempt at a Solution[/h2] I tried using H as my y value from eq. 1 and D as my x value in eq. 2. I solved for v[SUB]0[/SUB] 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? [/QUOTE]
