A 150 N box is being pulled horizontally in a wagon accelerating uniformly at 3.00 m/s2.The box does not move relative to the wagon,and the coefficient of static friction between the box and the wagon's surface is 0.600.The static friction force on this box is 90.0 N.

Question

Quizplus · Accepted Answer

The static friction force is equal to the product of the mass of the box and the acceleration of the wagon, which is less than 90.0 N.
