Tension in String for 0.25 kg Ball Revolving at 2 Hz

[Alexs45]

A 0.25-kg ball attached to a string is rotating in a horizontal circle of radius 0.5 m. If the ball revolves twice every second, what is the tension in the string?

T (tension)= m*(v^2)/R
And v (speed) You can find from frequency!?

Don't double post in the future; look at the following link:

[Alexs45]

so do you just plug the numbers into that formula and if it revolves twice every second does that effect the problem.

 

[Yegor]

You should represent velocity throgh the frequency
Or You can find velocity through v=s/t

do you mind doing out the problem because i am confused.like a step by step example..thank you so much Yegor

1.The tension in the rope/wire is a centripetal force.Which formula giving the centripetal force would be best to use in this case?
