A batter hits a pitched ball at a height of 4 feet above the ground so that its angle of projection is 45 degrees and its horizontal range is 350 feet.(adsbygoogle = window.adsbygoogle || []).push({});

The ball is fair down the left field line where a 24 foot high fence is located 320 feet from home plate.

By how much will the ball clear the fence?

vfy=viy+at

(vf)[tex]^{2}[/tex]= (vi)[tex]^{2}[/tex]+2aD (..we'll say D= displacement)

D= vi(t)+.5(a)(t[tex]^{2}[/tex])

Vx=Dx(t)

Well, I only really know my x displacement, my acceleration constant, and that my initial y velocity and my x velocity are the same because of the 45 degree triangle [at least that's what my teacher said]...

So, help?! It's been bugging me for days.
