Question: A string 3.2 m long and with a linear mass density of 0.008 kg/m is kept under tension so that traveling waves propagate at 48

A string 3.2 m long and with a linear mass density of 0.008 kg/m is kept under tension so that traveling waves propagate at 48 m/s along the string. The ends of the string are clamped and the string vibrates in its 3rd harmonic with an amplitude of 5.0 cm. How much energy is stored in this vibrating system at that time? If the amplitude of the standing wave diminishes to 3.0 cm in 1.0 s, what is the Q of this vibrating system?
