Solution
The type of force responsible for a change in the state of motion of the arrow is an example of a contact force.
Explanation:
Since muscular force can be applied only when in contact with an object, it is also called a contact force. Muscular force is a contact force applied when muscles contract, such as when the archer pulls back the bow string. This force stores potential energy in the bow.
