According to the law of inertia, Ms. Vetter will find it easier to push a box that is already in motion.
Let us recall that an object will move in in the direction of the larger force when an object is acted upon by a system of unbalanced forces. The honeybadger will move towards the left.
According to Newton's laws of motion, an object will continue in its state of rest or uniform motion unless it is acted upon by an external unbalanced force. Hence, the dummy flies out through the window because, the car pushes the object with such force that it causes the object to move forward, which makes the test dummy lunge forward through the windshield.
Again following Newton's law of inertia, a body tends to continue in its state of uniform motion hence so it is easier for Ms. Vetter to push the box that her Christmas tree is in, that is already moving instead of the same box that is stationary. The reason behind this is that, the force of friction on the object is different if it is stationary or not.
According to Newton's Third Law, if a sledgehammer hits a wall with a force of 1000 N, the force with which the wall hits the sledgehammer is - 1000 N.
