Subject: physics of hockey puck impacting goalie

OK, I'm interested in the calculation of just how hard a hockey puck hits 
the goal tender when launched, say, at 85 MPH.  I know it is 16oz, and about
1in in thickness...
How many pounds of force is the goalie's gear absorbing?

[note added by MadSci Admin: According to Section 3, Rule 25,
Part (a) of the pro hockey rule book, a puck is to be made of
vulcanized rubber, or other approved material, measure 3" in
diameter and 1" in thickness, and weigh between 5 1/2 and 6 
ounces.]
