A child is on the play ground they start to slide down a large slide. At what point is the child dynamic equilibrium with the slide

Answer 1

The child is in dynamic equilibrium with the slide when the forces acting on the child are balanced and there is no net acceleration. This occurs when the force of gravity pulling the child downward is equal to the normal force exerted by the slide upward. At this point, the child is sliding down the slide with a constant speed.
