which example best represents balanced forces?\no an elevator stopped on the third floor\no a basketball…

Brief Explanations:

Balanced forces occur when the net force on an object is zero and the object is either at rest or moving at a constant velocity. An elevator stopped on the third - floor is at rest, so the forces acting on it (gravity pulling down and the normal force from the floor pushing up) are balanced. A basketball shot into a hoop is in projectile motion with unbalanced forces (gravity and air resistance). A sled sliding down a hill is accelerating due to the component of gravitational force acting along the slope, so forces are unbalanced. A tow - truck pulling a car out of a ditch is applying a force to move the car, and there are resistive forces, resulting in unbalanced forces.

Answer:

an elevator stopped on the third floor
