Based on the information provided, the most accurate statement would be:
"It would be much easier to stop the duffel bag than it would be to stop a suitcase."
This is because, assuming all other factors (like friction, the surfaces they are on, and the materials of the bags) are the same, the duffel bag having less mass means it has less momentum when sliding. Therefore, it would require less force to bring it to a stop compared to the suitcase, which has more mass and thus more momentum.
The other statements are not necessarily true:
- "Both objects would be able to move at the same time": This is vague and doesn't relate directly to the mass comparison in terms of stopping them.
- "It would be more difficult to stop the duffel bag than it would be to stop the suitcase": This is incorrect since the duffel bag has less mass and momentum.
- "The duffel bag will contain warm matter than the suitcase": This has no relevance to the mass comparison or the dynamics of sliding across a floor.
So, the correct assertion based on the context provided involves the ease of stopping each object based on their mass.
