Detailed Solution

The above statement is true.
To stretch the bow, the archer pulls the thread of the bow backward, which changes the bow's shape. The force applied by the archer is an example of muscular or contact force because the archer and the bow on whose force is applied are in contact. The change in the state of the motion of the arrow is because of the gravitational force, which is a non-contact force. When an arrow is released by aiming it toward the target, gravity, as well as friction, acts on the arrow to oppose its motion of the arrow.
