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

Daniel.
