Two students drop an object into the sand from a height of 6.7 meters. They record the depth of the hole made by each object. What is the most likely explanation for the results? The depth of Sammy’s object was 4.2 and the depth of Jenny’s was 1.7

Responses
Sammy's object was moving faster when it hit the ground
Jenny's object had more potential energy before it was dropped.
Sammy's object had more kinetic energy when it hit the ground.
Jenny's object had less mass.
I think the answer is Sammy's object because it had more kinetic energy when it hit the ground, but I am unsure. Can you help confirm or say no?

Yes, you are correct. Sammy's object had more kinetic energy when it hit the ground. The depth of the hole made by an object dropped from a certain height is generally determined by its kinetic energy upon impact. As Sammy's object had a greater depth (4.2) compared to Jenny's object (1.7), it suggests that Sammy's object had more kinetic energy and therefore was likely moving faster when it hit the ground.
