A 0.50-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?
A)700 m/s
B)26 m/s
C)19 m/s
D)13 m/s

The maximum tension provides the centripetal force needed for circular motion: T = mv²/r. Solving for v, v = sqrt(Tr/m) = sqrt(350*1/0.5) = 26 m/s.
