Asked by AYDXN
I child is on a playground they start to slide down a large slide. At what point 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.

Answer: As the child is in motion as they are sliding down.
Reason: Dynamic equilibrium means the net force is zero while the object is moving (constant velocity). That happens when the downhill component of gravity is exactly balanced by friction/air resistance so the child slides at constant speed. Pushing causes acceleration (not equilibrium), and being stopped is static equilibrium (not dynamic).
