Question

A 0.050Kg yo-yo is swung in a vertical circle on the end of its long string at the slowest speed that the yo-yo can have.
What is the maximum tension in the string be when the yo-yo is swung in a vertical circle at this speed?
Where will this maximum tension occur? include a labelled FBD with your answer.

Guys, i've done this question 2 ways. Please tell me which one is correct.

Answer 1

Maximum speed and tension will be at the bottom of the circle/path

Answer 2

I'll get to you later, busy rn

Answer 3

yeah

Answer 4

it's k :)

Answer 5

\[\sum F = ma_c\]
\[T-mg = \frac{mv^2}{r}\]

Answer 6

The question gave you mass only?

Answer 7

and the length of the string which is 0.30 meters long.

Answer 8

The tension at the bottom of the string is 2.94N

Answer 9

You got it!

Answer 10

You can use conservation of energy for this problem too

Answer 11

ok one more question and im done for the day i promise!!

Answer 12

Sure
