a light string can support a stationary hanging load of 25 kg before breaking. an object of mass m = 3 kg attached to the string rotates on a frictionless horizontal table in a circle of radius r = 0.8 m and the other end of the string is held fixed. what range of speeds can the object have before breaking

Question

anonymous · Answer

You need to find the linear force necessary to break the string first.  How many Newtons does 25 kg produce assuming standard (earth's surface) acceleration due to gravity?  Can you do this step first?

25 x 9.8?

anonymous · Answer

$\huge \text{Force} = m * a = \frac{m*v^2}{r}$
m = mass
a = acceleration
v = your tangential speed
r = radius
