Question

a. To stretch the bow, the archer applies a force that causes a change in its ______
b. The force applied by the archer to stretch the bow is an example of ______ force.
c. The type of force responsible for a change in the state of motion of the arrow is an example of a _____ force.
d. While the arrow moves towards its target, the forces acting on it are due to ______ and that due to _______ of air.
A. Shape
B. Muscular
C. Contact
D. Gravity, Friction

Answer 1

There are some forces which are responsible for some specific acts like stopping a body, pulling a body bending a body, here we need to answer the question in that way, when the body moves some fixed forces acts on the body we have to get the name of the forces.

Complete answer:
The answer to the above questions are:
a. To stretch the bow, the archer applies a force that causes a change in its shape.
For question A answer is option A that is shape.

b. The force applied by the archer to stretch the bow is an example of muscular force.
For question B answer is option B that is Muscular.

c. The type of force responsible for a change in the state of motion of the arrow is an example of a contact force.
For question C answer is option C that is contact.

d. While the arrow moves towards its target, the forces acting on it are due to gravity and that due to Friction of air.
For question D answer is option D that is gravity, friction.

Note:
- When the string of the bow is stretched the string is connected to the body of the bow at both ends that’s why when we apply force to the string the bow also bends. Thus changing its shape and giving the arrow more energy when released.
- When the archer pulls the bow they apply muscular pressure that is the pressure from the muscles. To change the state of the motion that is the body is moving or not moving a body will stop to move only when it is opposed by some force and that force can only be applied when there is a contact so contact force is needed to change the state.
- When any object is in air only two forces act on the body one is the frictional force of the air that is the friction that the air has and another force is the earth that tries to pull the body towards itself that is the gravitational force.
