URGENT
THIS IS WHAT IT SAYS:
A certain string can withstand a maximum tension of 46 N without breaking. a child ties a 0.38 kg stones to one end and, holding the other end, whirls the stone in a vertical circle of radius 0.85 m, slowly increasing the speed until the spring breaks. (a) where is the stone on its path when the string breaks (top of the circle, middle of the circle, or bottome of the circle?) (b) what is the speed of the stone as the string breaks?

(b) What is the speed of the stone as the string breaks? Click if you would like to Show Work for this question:Explanation / Answer
a) bottom of the circle
b) Tmax = m*g + m*v_max^2/r
Vmax = sqrt(Tmax*r/m - g)
= sqrt(46*0.85/0.38 - 9.8)
= 9.65 m/s
