Question

use the table of information from a students investigation to answer the question.
splash size ranking of objects
a student drops several objects of the same size into a bucket of water from a height of 2 meters. she ranks the splash size from 1 - 4, with 1 being the smallest splash and 4 being the largest splash. which object most likely has the greatest mass?
(1 point)
object x
object w
object z

Explanation:

When objects of the same size are dropped from the same height, the object with the greatest mass will have the most kinetic energy upon impact. Kinetic energy \(KE=\frac{1}{2}mv^{2}\) (where \(m\) is mass and \(v\) is velocity). Since they are dropped from the same height, their velocities just before impact are the same. A larger mass means more kinetic energy. More kinetic energy results in a larger splash. Object \(X\) has the highest splash - size ranking (4), which indicates it has the most kinetic energy among the objects, and thus the greatest mass.

Answer:

object X
