Explanation:
How does air resistance affect an object's landing time, and what variables does air resistance depend on? A: When an object is dropped from rest (and we ignore air resistance) the time it takes to reach the ground depends only on the initial height and the acceleration of the object.
Time of ascent; During ascent of projectile, both weight of projectile and air resistance act in downward direction.So, net acceleration in downward direction increases . Thus, time ascent decreases due to air resistance.
Time of descent; During descent of projectile , though weight of projectile act in downward direction but the air resistance acts in upward direction. (As, it opposes the motion) Because of this, net downward acceleration decreases and time of descent increases.
