Question

When a bow an arrow is fired, how does the size of the force of the bow on the arrow compare of the arrow on the bow

Answer 1

Stated by Newton's 2nd Law of Motion, the arrow will exert an equal force on the bow as the bow exerts on the arrow. So if the bow applies 2 Newtons of force on the arrow, the arrow will apply 2 Newtons of force back on the bow.
