Use the table of information from an investigation to answer the question.
Student Depth of Object in Sand (cm)
Maddie 1.8
Naveed 4.0
Two students drop an object into sand from a height of 1.5 meters. They record the depth of the hole made in the sand by each student’s object. What is the most likely explanation for the results?
a
Naveed's object had greater kinetic energy
b
Maddie's object had a faster drop speed
c
Naveed's object had less mass
d
Maddie's object had a smaller width
c. Naveed's object had less mass. This would allow it to penetrate deeper into the sand despite having the same initial kinetic energy as Maddie's object.
To determine the most likely explanation for the results, we need to analyze the information provided. The table shows the depth of the object in the sand for two students, Maddie and Naveed.
Maddie's object has a depth of 1.8 cm, while Naveed's object has a depth of 4.0 cm.
Since both objects were dropped from the same height of 1.5 meters, we can conclude that the difference in depth is unlikely to be due to the drop height.
Considering the given options, the most likely explanation for the results is:
c) Naveed's object had less mass.
If Naveed's object had less mass compared to Maddie's object, it would experience less resistance from the sand, allowing it to penetrate deeper. This would explain why Naveed's object reached a greater depth in the sand compared to Maddie's object.
To answer this question, we need to analyze the information provided in the table. The table shows the depth of the object in the sand for each student: Maddie's object went 1.8 cm deep, while Naveed's object went 4.0 cm deep.
Since both students dropped their objects from the same height, we can infer that the difference in the depth of the holes is likely due to the objects' characteristics.
The most likely explanation for the results can be determined by considering the concepts of kinetic energy and mass.
Kinetic energy is defined as the energy of an object due to its motion. The equation for kinetic energy is KE = (1/2)mv^2, where m is mass and v is velocity.
From the information given in the table, we don't have any information about the velocity of the objects. Therefore, we cannot determine their kinetic energies.
However, we do have information about the depth of the holes made by each object. The depth of the hole can be an indication of the impact force, which is directly related to the object's mass.
Given that Naveed's object made a deeper hole than Maddie's object, it can be inferred that Naveed's object had more mass. Therefore, the most likely explanation for the results is that option c, "Naveed's object had less mass," is the correct answer.
To summarize, the most likely explanation for the results is that Naveed's object had less mass compared to Maddie's object, causing it to make a deeper hole in the sand.
