title: How to throw a ball to a specific point on plane?
body: <p>I'm trying to have catapult-like mechanism for shooting a ball at a specific point. For example, starting position of the ball is x=0, y=.5, z=0, and I want it to end up at x=10, y=0, z=20.  For now I'm using:</p>
  
  <pre><code>RigidBody.AddForce(new Vector3 (10, 15, 20) * thrust);
  </code></pre>
  
  <p>I'm averaging out 'y' element to between x and z, but thrust seems the most complex to calculate, I've tried estimating it by trial+error, but that can't the the correct solution.</p>
