JoeTang Wrote:Your equation isn't considering drag. Also, your acceleration assumption is wrong. I don't think it's possible to determine acceleration because the force applied is based on the acceleration change between the moment it impacts the skin and the moment its velocity is zero, not the moment between the time it exits the barrel and then stops.Considering drag is complicating things beyond the "rough estimate" that was asked for. And yes, my assumption is wrong, but there's not much else to go on. You're more than welcome to post your own answer to the question.
