I'm trying to figure out if it is possible to accurately calculate the mass of a granular material (something like grain) impacting a very rigid object (a fixed metal plate) if the velocity of the granular material, impact force, and time of impact are known. After googling around a bit I've come up with the following formula:(adsbygoogle = window.adsbygoogle || []).push({});

m = (impact force * time of impact) / (velocity of granular material)

Am I on the right track or way out in left field? What are some of the important things to consider when trying to measure mass in this way?

Physics is not a strong-point of mine so any help would be greatly appreciated.
