(20 14? As shown in the figure, Xiaoyu exerts a horizontal thrust on the box. The following statement is wrong: () A. When the thrust is 75N, the box does not.

A, when the thrust is 75N, the box does not move, and the static friction on the box is equal to the thrust, so this option is correct, but it does not meet the meaning of the question;

B, when Xiaoyu increases the thrust, the box starts to move from rest, indicating that the force can change the motion state of the object, so this option is correct, but it does not meet the meaning of the question;

C, when the thrust is 100N, the box moves in a straight line at a uniform speed, and the sliding friction of the box is equal to the thrust, so this option is correct, but it does not meet the meaning of the question;

D. When the box moves in a straight line at a uniform speed, the box moves for a distance under the thrust of people, so the old friend has done work on the thrust of the box, so this option is wrong and in line with the meaning of the question;

So choose d
