Sagot :
--- Because the inertia of the bull is much higher than the man so bull gains more momentum on each step but while running in the zig-zag pattern the bull has to apply the force against the momentum it has created and move in the opposite direction but in the man’s case the man is much lighter than the bull which means less inertia resulting in less momentum which makes man easier o move in zig-zag pattern than a bull, by the way, newton’s first law of motion states that “A body remains at rest and a body in uniform speed remains in uniform motion unless an external force is applied to it”
