A student drops a 350-gram rock and a 500-gram rock into a pool from a height of 8 meters. Which statement about the investigation is accurate?(1 point)

Responses

The 500-gram rock causes a smaller splash because it has more mass.
The 500-gram rock causes a smaller splash because it has more mass.

The 350-gram rock causes a smaller splash because it has more kinetic energy.
The 350-gram rock causes a smaller splash because it has more kinetic energy.

The 350-gram rock causes a larger splash because it has less mass.

The most accurate statement about the investigation is:

The 500-gram rock causes a larger splash because it has more kinetic energy.

When both rocks are dropped from the same height, they will have the same potential energy when released (potential energy = mass × gravity × height). However, since the 500-gram rock has more mass, it will have greater kinetic energy upon impact, leading to a larger splash.
