How to call acceleration of thrown object?

Hello,

I am trying to experiment with a sound detection formula as part of a stealth mechanic for a VR game. I’d like to calculate the force of a thrown object as a starting value before adding additional modifier values. My thinking (unless there’s a better means of doing so) is to manually calculate the force through force=mass*acceleration. I have been able to figure out getting the mass of the actor, but I’m having difficulty on determining it’s acceleration when thrown.

What would be the best means of getting the acceleration of a thrown actor in order to multiply it against the actor’s mass set in the Physics details?
