Question

force and motion concepts quick check
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? (1 point)
when the child pushes themselves down the slides.
as the child is in motion as they are sliding down.
when the slide ends and the child has stopped moving.
the child will not reach dynamic equilibrium.

Explanation:

Dynamic equilibrium occurs when an object is moving with a constant velocity, meaning the net - force acting on it is zero. When a child slides down a slide, there is friction and gravitational force acting on the child. The forces do not balance out to result in a net - force of zero while sliding (due to acceleration or non - zero net force), and when stopped, it's static equilibrium. So the child will not reach dynamic equilibrium while sliding down the slide.

Answer:

The child will not reach dynamic equilibrium.
