Achild\'s top is held in place, upright on a frictionless surface. the axle has a radius of r = 2.96 mm. two strings are wrapped around the axle, and the top is set spinning by applying t = 2.40 n of constant tension to each string. if it takes 0.740 s for the string to unwind, how much angular momentum does the top acquire? assume that the strings do not slip as the tension is applied.
