Question

a student is conducting an experiment in which she drops a ball from four different heights. her work is shown below: fall time from four different heights (s) height 1 height 2 height 3 height 4 0.61 0.78 1.00 1.09 0.58 21.63 1.05 1.21 0.68 0.82 1.10 1.18 0.57 0.84 1.15 1.19 0.60 0.75 1.20 1.28 1. the student wants to estimate the fall time for height 1. how should she do this? report that the time is between 0.57 s and 0.68 s calculate the average (0.608 s) just report the first measurement (0.61 s) put the five times in order and choose the median, or middle number (0.60 s)

Answer 1

To estimate the fall time for height 1, the student should calculate the average fall time by adding the recorded times together and dividing by the number of trials, resulting in an average time of 0.608 seconds.

Step-by-step explanation:

To estimate the fall time for height 1, the student should calculate the average of the collected times. This is the most statistically reliable method as it minimizes the impact of anomalies and random errors that may occur during individual trials.

To calculate the average fall time:

1. Add up all the fall times recorded for height 1.
2. Divide the sum by the number of trials conducted (which is 5 in this case).

The calculation would be (0.61 + 0.58 + 0.68 + 0.57 + 0.60) / 5 = 3.04 / 5 = 0.608 seconds.

Therefore, the student should report the average fall time as 0.608 seconds for height 1.
