Default Wrist Rocket Height

Tim- from my High school Physics== the Formula is: F= MA
Force = Mass Times Acceleration. Perhaps a Bow and Arrow
will exceed the (Wrist Rocket) in this department? at 50#
Pull for Acceleration? (Oz per Oz) Jim NN7K


more relevant is the 2ad=v^2 equation... height goes as the square of
the launch velocity, neglecting air drag and line drag.

but, where the bow and arrow really excel is in the overall larger mass
of the projectile and higher launch energy (mostly the latter. the arrow
is a couple or three ounces.. same as the wrist rocket.. but the bow
will easily have a 50 lb draw and longer distance.

See, e.g., http://www.stortford-archers.org.uk/medieval.htm for some
discussion of bow and arrow physics
