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) Responses Jade Jade Ziva Ziva Owen Owen Eduardo

Answer 1

To determine which student most likely had an error in their results, we can analyze the recorded times for each ball.

1. Ziva: Ball 1 (0.52s), Ball 2 (0.51s), Ball 3 (0.51s)
2. Jade: Ball 1 (0.51s), Ball 2 (0.52s), Ball 3 (0.52s)
3. Eduardo: Ball 1 (0.50s), Ball 2 (0.50s), Ball 3 (0.50s)
4. Owen: Ball 1 (0.50s), Ball 2 (0.37s), Ball 3 (0.51s)

Eduardo’s results show a consistent time for all three balls, which is unusual since we would expect minor variations due to factors such as air resistance or minor differences in the falling paths.

Owen's time for Ball 2 (0.37s) is significantly lower than those recorded by the other students for the same ball, which indicates a potential error in measurement.

Given this analysis, it is most likely that Owen had an error in his recorded results.
