A string of length 2.4 m consists of two sections with equal length.The left half has mass per unit length 0.00025 kg/m, while the right has a mass per unit length 0.00075 kg/m. Tension in the string is 989 N. Notice from the data given that this string has the same total mass as a uniform string of length 2.4 m and mass per unit length 0.0005 kg/m.
(a) Find the speed at which transverse wave pulses travel in the left section. Answer in units of m/s.
(b) Find the speed at which transverse wave pulses travel in the right section. Answer in units of m/s.
(c) Find the time required for a pulse to travel from one end of the string to the other. Answer in units of s.
