Questions: 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.

Solution

Solution Steps

Step 1: Understanding Dynamic Equilibrium

Dynamic equilibrium occurs when an object is moving at a constant velocity, meaning there is no net force acting on it. In this state, the forces acting on the object are balanced, but the object is still in motion.

Step 2: Analyzing the Child's Motion

As the child slides down the slide, they are accelerating due to gravity, which means there is a net force acting on them. Therefore, they are not in dynamic equilibrium while sliding down.

Step 3: Evaluating the Options

When the child pushes themselves down the slide: This involves an initial force, so the child is not in dynamic equilibrium.
As the child is in motion as they are sliding down: The child is accelerating, so they are not in dynamic equilibrium.
When the slide ends and the child has stopped moving: The child is not in motion, so this is not dynamic equilibrium.
The child will not reach dynamic equilibrium: This is the correct option because the child is either accelerating or at rest, but never moving at a constant velocity without net force.
