Which describes how sliding friction affects pushing a cereal box across a tabletop?

It is usually greater than static friction.

It acts in the direction of motion.

It equals the weight of the box.

It acts in the direction opposite of motion.

It acts in the direction opposite of motion.

Explanation:

The sliding friction is the one offering resistance to motion of the sliding cereal box. This force is created between the box and the tabletop that are sliding against each other. The sliding friction is proportional to the weight of the cereal box when pushed on the horizontal tabletop. We can apply the Newton's second law of motion to describe this motion, where force is a product of mass and acceleration. When the object is massive, the sliding friction force experienced is high thus sliding happens slowly.
