Throw Object Slowly

Hi,

I want to throw a ball with rigidbody.AddForceAtPosition(mDirection, mPosition); Where is mDirection = new Vector3(mDirTmp, 300, 200); to throw the object as in "Paper Toss"

But the problem is that sometimes, the ball penetrates others static object. The ball has a Rigidbody and a mesh collider (it's not a perfect sphere so native collider can't be used), and other objects are static object with mesh collider. I think that if the ball penetrates other objects, it's because of its speed. Even with the script DontGoThroughThings it happens. And the rigidbody.velocity.magnitude dont go above 3.

Thanks for any help.
