B)non-dynamic equilibrium.
C)being in and out of dynamic equilibrium.
D)none of the above

Question

Quizplus · Accepted Answer

When a parachutist falls at a constant velocity, the forces acting on the parachutist are balanced. The force of air resistance is equal to the force of gravity pulling the parachutist down. This state of balance is called dynamic equilibrium, where there is no net force acting on the parachutist. Therefore, choice A is the best answer.
