Two balls are tied together via string and then swung in a vertical circular path using a
second string, as shown in the figure. During this motion, the two strings are co-linear at all times.
The first ball has mass m1 = 0.4 kg, and the second has m2 = 0.2 kg. Each of the two strings has an
individual length l = 36 cm. At the top of its swing, m, is traveling at v = 3.0 m/s. (a) What is the
tension in String 1 at this instant? (b) What is the tension in String 2 at this instant? (c) Which
string will break first if the combination is rotated faster and faster? (i.e. which tension will grow
too large?)
