Answer:
(D)
Explanation:
You can input any value for x and the result will be a real number
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
Well it depends on how big the swimming pools are like one of those big ones or the kid ones also I’m thinking if it’s the little ones that’s it’d be like a 10 years but the big ones omg I have no clue
