When a bow is pulled back with the arrow in place, elastic potential energy is stored in the bow and thus arrow. When released, all that potential energy is converted into kinetic energy. EPE=KE. Since you know the "pounds" of the bow, the weight of the arrow, and how high the arrow is from the ground you can calculate the an arrows range assuming it is parallel to the ground. Derivation: KE= .5 X Mass X Velocity^2 Distance= Velocity X Time Time the Arrow is in Flight= [( vertical distance x 2)/ (32 ft/sec^s)]^(1/2)
