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 phrases from each of the sentences are most likely:
- <u>Participial phrase
</u>
- <u>Infinitive phrase
</u>
- <u>Gerund phrase</u>
- A participial phrase is the collection of words in a sentence which is made up of a participle, and a modifier. They perform various functions in a sentence such as being either the objects, or adding extra meaning to the word.
- An infinitive phrase is a group of words which has an infinitive and also gives extra information about another word.
