Explanation:
When the archer shoots the arrow, force sets the arrow in motion which is called as the Muscular Force. The frictional force on air acts would become the main cause for the free flow of the process and the speed of the arrow gets decreased gradually when it falls down.

The archer stretches the string of the bow by applying muscular force. In the process the shape of the bow changes. When the string is released, it regains its original
position that provides the initial force to set the arrow in motion. The force of gravity that acts on the arrow in the downward direction brings it to the ground.
