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)

Question

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 larger splash because it has less mass.
The 350-gram rock causes a larger splash because it has less 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 500-gram rock causes a larger 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 the rocks are dropped from the same height, they both fall under the influence of gravity, gaining kinetic energy as they fall. The kinetic energy of an object in free fall is given by the formula \( KE = \frac{1}{2}mv^2 \), where \( m \) is the mass and \( v \) is the velocity. Since the 500-gram rock has a greater mass, it will have more kinetic energy upon impact compared to the 350-gram rock, resulting in a larger splash.
