Problem 6.02 Part A A stone with a mass of 0.800 kg is attached to one end of a string 0.800 m long. The string will break if its tension exceeds 65.0 N. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed. Find the maximum speed the stone can attain without breaking the string.
