Final answer:

To calculate work done, both force and distance need to be known. Without this information, we cannot determine how much work was done by the movers pushing a 46.0-kg crate.

Step-by-step explanation:

The amount of work done by the movers in pushing a 46.0-kg crate horizontally cannot be determined from the information provided in the question alone. Work, in the context of physics, is defined as force applied over a distance (W = F × d), and is dependent on both the magnitude of the force applied to the crate and the distance over which the force is applied. If either the force or the distance is not provided or cannot be inferred from the context, we cannot calculate the work done.

Based on the information provided in the question, the correct answer would be B) Not enough information, since we do not know the distance the crate was moved or the force applied. It is also important to note that if the crate was pushed horizontally at a constant speed, it implies the net force was zero (due to Newton's first law of motion), and hence the work done by the movers against friction would be equal to the frictional force times the distance moved.
