The solutions are 7, - 7, 2, - 7
The tension in the string balances out, and thus equals the centripetal force of the ball
T = mv^2/r
<span>
if it only takes half the time to finish one orbit it has to be moving at twice the original speed. </span>
<span>
And since v is squared T will increase by 4 </span>
<span>
T' = m(2v)^2/r </span>
<span>
T' = 4mv^/r = 4T </span>
<span>
T' = 24.0 N
I hope my answer has come to your help. Have a nice day ahead and may God bless you always!

Find the amount of points each student earned!
Erika: 100 x 0.84 = 84 points earned out of 100.
Joe: 100 / 6 = 16.6667... x 5 = 83.333... = 83.3 points earned out of 100.
Malcolm: √7225 = 85 points earned out of 100.
Stephanie: 83/100 = 83 points earned out of 100.
