A student drops several objects of the same size into a bucket of water from a height of 2 meters. She ranks the splash from 1-4, with 1 being the smallest splash and 4 being the largest splash. Which object most likely has the greatest mass?

The object that most likely has the greatest mass is the one that creates the largest splash, which would be ranked as a 4. The larger the splash, the more force is required to create it, indicating a greater mass of the object being dropped. Therefore, the object ranked as a 4 would have the greatest mass.
