How to Predict Grenade Trajectory Positions?

I attached a youtube video as an example incase you don't understand.

Basically my NPC's throw grenades simple by using rigidbody.velocity

As the grenade is thrown I instantiate a sphere every 0.1 seconds and draw an arrow from the previous sphere position to the new sphere position. I rinse and repeat this until it hits the ground. This shows the trajectory while it is airborne.

Once it hits the ground it rolls a bit more from the momentum before stopping. Is there any way for me to get/capture/predict these positions before it actually happens?

Or better yet can I get/predict all the positions from start to finish before it actually happens?

The few trajectory prediction assets on the store seem to predict the positions while the grenade is airborne mainly. Does anyone know an asset that can also predict the positions while it rolls around on the ground? or is there any easy method to achieve this?

Thanks a lot.

 

I think that the new multi-scene physics feature in Unity 2018.3 fits your case perfectly. Check out this blog post:

Scroll down to "Multi-scene physics" and you'll find a video with a very similar example.
