Consider a collision between a large and small body (golf club/hockey stick/baseball bat and a ball for example). How is it possible to calculate how much the momentum of parts of the body removed from the collision contact point have an effect on the momentum of the smaller body before it accelerates away?
Many people think that since the contact duration is so small (as little as half a millisecond in some cases), that only the part of mass in the vicinity of the collision matters (i.e. the effective mass).
However, how do you calculate this? Is it something to do with the speed of propogation of elastic stress waves?
