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

Once the arrow is shot with constant velocity, the only force acting on it is the downward force of gravity neglecting air resistance. It will continue to fly horizontally at the constant velocity until it hits the ground.
