Two Sumo wrestlers push against each other in a match. At first, wrestler A gets pushed backwards two steps, but then they stop moving even though they are still pushing against each other. Why did this happen?
At first the forces are unbalanced, then wrestler B pushes with a greater force
until the forces are balanced.
