It would be static friction which is what you have to overcome when an object is not in motion. When you move an object friction works against it like gravity and air resistance. I hope this helps!

Answer:

Static friction.

Explanation:

Static friction is defined as the force of friction that keeps an object at rest position.

This friction must be overcome to start an object moving . If an object is in motion, it will experiences a force of friction called kinetic friction.

If a force is applied which is of small magnitude to an object, the static friction will posses or applies an equal magnitude which is in opposite direction of applied force.

sp2606 [1]

Force exerted by the bullet = mass * acceleration = 0.013 * 850 = 11.05 Newtons.

the rifle exerts same force in opposite direction so we have

11.05 = 3.5 * a
acceleration = 11.05 / 3.5 = 3.16 m /s^-2
