title: Calculating Intercepting Vector
body: <p>I have 2 objects (i'll refer to them as <strong>target</strong> and <strong>interceptor</strong>).
  I know the target's current location and velocity.
  I know the interceptor's current location and speed it can travel.</p>
  
  <p>From that, what I now need to know is :</p>
  
  <ul>
  <li>Is interception possible ie same location at same point in time.</li>
  <li>What vector would the interceptor need to travel on</li>
  <li>How much time will the interception take</li>
  </ul>
  
  <p>i.e target @ (120,40) with a V(5,2) per second and interceptor @ (80,80) that can travels with a speed of 10 per second.</p>
  
  <p>I've looked around and found plenty of ways to find out what point they meet and they all revolve around the angle between the two vectors and as I don't know the second vector and I can't calculate that and I'm getting lost trying to resolving this.</p>
  
  <p>Any suggestions or guidance on how to proceed are appreciated.</p>
