Answer 1

Dynamic equilibrium occurs when an object is moving at a constant velocity and the net forces acting on it are balanced. In the context of the child sliding down the slide, the most appropriate point where the child would be in dynamic equilibrium would be:

The child will not reach dynamic equilibrium.

When the child is sliding down, they are accelerating due to gravity, and therefore are not in dynamic equilibrium. Dynamic equilibrium would not be achieved until the child reaches a state of constant velocity, which typically does not occur in a slide situation without external forces acting on them (like friction slowing them down). Therefore, the best answer here is that the child does not reach dynamic equilibrium during the sliding process.
