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 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 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 500-gram rock causes a larger splash because it has more kinetic energy.
The 500-gram rock causes a larger splash because it has more kinetic energy.
The 350-gram rock causes a larger splash because it has less mass.
The 500-gram rock causes a larger splash because it has more kinetic energy.
