Use the table of data from an investigation on the effect of gravity on falling objects to answer the question.

Question

Student] Ball 1 (seconds)] Ball 2 (seconds)] Ball 3 (seconds)]
Ziva 0.52 0.51 0.51
Jade 0.51 0.52 0.52
Eduardo 0.50 0.50 0.50 `
Owen 0.50 0.37 0.51

Four students investigated the effect of gravity on falling objects. The students all used the same three balls and dropped them from a height of 8 meters. They recorded the time it took for each ball to hit the ground. Which student most likely had an error in the results?(1 point)

A) Ziva
B) Jade
C) Eduardo
D)Owen

Answer 1

To determine which student most likely had an error in their results, we can analyze the completion time recorded by each student for the three balls.

• Ziva: 0.52, 0.51, 0.51 seconds
• Jade: 0.51, 0.52, 0.52 seconds
• Eduardo: 0.50, 0.50, 0.50 seconds
• Owen: 0.50, 0.37, 0.51 seconds

Here, Owen recorded a sudden drop in the time for Ball 2 (0.37 seconds) that is significantly lower than the other times recorded by all students (ranging from 0.50 to 0.52 seconds). This drastic difference indicates that he likely made an error in measuring the time it took for that ball to hit the ground.

Therefore, the student who most likely had an error in the results is:

D) Owen
