A0.50 kg toy is attached to the end of a 1.0 m very light string. the toy is whirled in a horizontal circular path on a frictionless tabletop. if the maximum tension that the string can withstand without breaking is 350 n. what is the maximum speed the mass can have without breaking the string?

The maximum speed will be 26.475 m/sec

Explanation:

We have given mass of the toy m = 0.50 kg

radius of the light string r = 1 m

Tension on the string T = 350 N

We have to find the maximum speed without breaking the string  

For without breaking the string tension must be equal to the centripetal force

So

So

v = 26.475 m /sec

So the maximum speed will be 26.475 m/sec

trig 15.3 cos

the answer is b i think
