Concept

Problem: A bullet fired from a rifle begins to fall(a) as soon as it leaves the barrel(b) after air friction reduces its speed(c) not at all if air resistance is ignored

FREE Expert Solution

The relative motion of an object in the air depends on the mass and the velocity of the object.

Also, air resistance opposes the relative motion of an object. 

The object will fall with terminal speed in the case where the force of the air resistance is equal to the gravitational force.
