Physics problems in the second day of junior high school. . As shown in the picture, Xiaogang pushes a car parked on a level ground with a force of 200N N.

I don't see your picture, but look at the description of the topic. Cars are only subjected to horizontal thrust and friction. Because it is stationary, it is subjected to static friction, which is equal to the thrust of 200N N N. In fact, we can also know that the thrust is 200N. If the friction is >; 200N, the resultant force in the horizontal direction of the car is not zero, so it will not stand still relative to the ground.
