Find the quality factor of the oscillator whose displacement amplitude decreases ` eta =2.0` times every `n=110` oscillation.

A ball of mass m=50 g is suspended by a weightless spring with stiffness x=20.0 N//m . Due to external vertical harmonic force with frequency omega=25.0 s^(-1) the ball performs steady - state oscillations with amplitude a=1.3 cm . In this case the displacement of the ball lags in phase behind the external force by varphi=(3)/(4)pi. Find : (a) the quality factor of the given oscillator , (b) the work performed by the external force during one oscillation period.
