Responses

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

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

Answer 1

The 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 hit the water with different kinetic energies due to their different masses. The kinetic energy (KE) of an object in free fall can be calculated using the formula KE = 1/2 mv², where m is the mass and v is the velocity just before impact. Since the 500-gram rock has a greater mass, it will have more kinetic energy at the moment it hits the water, likely resulting in a larger splash.
