An arrow is given an initial velocity from the bow with which it is shot. Assuming that the air resistance is negligible, once the arrow leaves the bow,

Question

A. it requires another force to keep it moving.

B. it accelerates horizontally until it stops moving.

C. it moves with a positive vector to the ground.

D. the only force acting on it is the force of gravity

Answer 1

(A) Not the answer because the bow force is what propels the arrow to move

(B) No air resistance therefore constant velocity on the horizontal direction.

(C) The direction of position and velocity is negative as it travels

(D) this is correct, in free flight the only force is due to gravity. Mass * gravity,
