Grab and throw of an object in Immersive mode

Hi Team,
Currently we are implementing a Basket ball game in immersive mode(VR).
As we know that to implement basket ball game we have two major functionalities those are grabbing the ball and throwing the ball with the force that user applies.
So far we can able to implement the grab functionality but for throwing functionality we are not able to proceed properly. Here we need guidance for throwing an object with the user applied force in immersive mode using controllers.
So can someone guide us for throwing functionality using controllers in immersive mode, also please share any reference that would be more helpful.
