<h3><u>Answer;</u></h3>

D) A sky diver reaches terminal velocity when he stops accelerating.

<h3><u>Explanation;</u></h3>
  • <em><u>Balanced forces are forces that act in opposite directions and are equal in size. </u></em>When an object is acted upon by unbalanced forces then the object stays still or at rest or continues moving at a constant velocity in the same direction.
  • Unbalanced forces cause an object or a body to change its motion or velocity and direction.
  • <u><em>A sky diver who reaches terminal velocity when he stops accelerating, experiences balanced forces. Terminal velocity being a point at which the drag force is equal to the force of gravity.</em></u>
