Answer:
Dynamic equilibrium
Step-by-step explanation:
This is because dynamic equilibrium is when the body is set on motion at constant velocity. When humans are walking, when achieve unstable equilibrium that is not static or dynamic on the first foot and a non equilibrium when the other foot is involved. In human movement,it is at constant velocity and the Total number of forces acting is zero. This type of equilibrium always return to it's initial point after disturbances since humans did not continually walk all the time .
