Luke1294 said:Hm. So, I was looking at that the wrong way for sure. That can definatly be written as [tex]140.238= 288cos\theta sin\theta[/tex], can't it? So, I divide both sides by 144...giving me [tex].973875=2sin\theta cos\theta[/tex], or [tex].973875=sin(2\theta)[/tex]. I then divide the left by 2, take the inverse sin, and arrive at 29 degrees?
Am i error free?! Finally?!
luke, how did you get 14.3 for x? doesn't 14.3 = the momentum of the rock?
