A representative sample

Explanation:

A representative sample is a group that closely resembles the characteristics of the population from which the sample was drawn. This means that the sample closely reflects the population, and therefore, the results we get from the sample would likely be valid for the population as well. If the sample we use is not representative of the population, then the conclusions we reach would most likely not hold true in the population at large.

since the height of the building is 29.3 meters then:

the ball was in motion for approximately 2.45 seconds
