Fruit. Mass (kg). Speed (m/s)
Watermelon. 4. 2
A
Watermelon. 4. 4
B
Two watermelons fall off a kitchen counter. The masses and speeds of the fruits are in the table. How do the kinetic and/or the potential energies of the fruits compare?
The watermelon B

Answer
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)
The 500-gram rock causes a larger
• splash because it has more kinetic energy.
The 350-gram rock o causes a larger splash because it has less mass.
The 500-gram rock causes a smaller splash because it has more mass.
The 350-gram rock causes a smaller
O splash because it has more kinetic energy.

I apologize for the incorrect response. The correct statement is:
The 350-gram rock causes a larger splash because it has more kinetic energy.
The 350-gram rock causes a larger splash because it has more kinetic energy.

I apologize for the confusion. The correct statement is:
The 500-gram rock causes a larger splash because it has more mass.
The kinetic energy of an object is directly proportional to its mass. Therefore, the greater mass of the 500-gram rock results in a larger kinetic energy and, consequently, a larger splash when dropped into the pool compared to the 350-gram rock.

The object most likely to have the greatest mass is object X, as it creates the largest splash (ranked 4) when dropped into the bucket of water.
