A child is on a playground they start to slide down a large slide at what point is the child in dynamic equilibrium with the slide

Answer 1

Dynamic equilibrium occurs when an object is moving at a constant velocity and experiencing no net force acting on it. In the case of a child sliding down a slide, they are considered to be in dynamic equilibrium when the gravitational force pulling them down the slide is balanced by the forces of friction and any normal force acting perpendicular to the slide surface, resulting in no acceleration.

To summarize, the child is in dynamic equilibrium at the point where they are sliding down the slide at a constant speed, meaning the forces acting on them (gravity, friction, and normal force) are balanced. This typically happens when the child has reached a steady speed after initially accelerating down the slide.
