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. true or false

Since the wagon is staying attached to the ground, the normal force of the wagon balances the weight of the wagon. This means that the normal force is:

`N=150` newtons

Also, the coefficient of static friction is 0.6, so the frictional force is:

`F=0.6(150)=90` newtons.

The force due to friction is 90 newtons.
