Want this question answered?
Velocity.
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
YES!
By an arrow, a vector. Velocity is a vector quantity that must have both magnitude (speed) and direction (bearing).
The magnitude of its Velocity (Speed), and its Direction. These are the components of the Arrow (Vector) that represents its MOTION.
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)
Broken Arrow was released on 02/09/1996.
The mass of the arrow does not affect the kinetic enery of the projectile. It does however affect the velocity of the arrow. The heavier the arrow the slower it flies ( out of the same bow). As far as penertation goes, velocity is your friend. There is alot of material science that goes into play but generally the faster projectile wins in penetration tests.
51 seconds.
A velocity vector would include both a speed and direction. Wind (air) resistance will affect the speed component, slowing down the arrow as time passes. Gravity will pull it downward at a constant acceleration of 9.8 m/s2. This means that the downward component of the velocity will increase with time. Wind, of course, could also throw the arrow off course.
This is a velocity question so u need to use uvaxt
force of gravity pulls the arrow down
