Explanation:
no it's you know for getting them for this
At the bottom of the circle, the ball is being pulled upward by tension in the rope and downward by its own weight, so that the net force on it is
∑ F = 450 N - (0.75 kg) g = (0.75 kg) a
where a is centripetal acceleration. At this maximum tension, the ball has a maximum centripetal acceleration of
a = (450 N - (0.75 kg) g) / (0.75 kg) = 590.2 m/s²
Then its maximum tangential speed v is such that
a = v² / (1.0 m)
⇒ v = √((1.0 m) a) ≈ 25 m/s
The author who quotes the video game researcher is using statistical argument.
<h3>What is statistical argument?</h3>
Statistical argument is an argument based on facts and figures from a research. This kind of argument requires the researcher to get values in order to make judgement.
Children who earn poor grades in school do well in playing video games. This is because, the researcher has found out how low they perform in class in terms of their test score and has used this as a measure to determine how poor they play video games.
