A 5.0-kg trout is attached to t4s bbmcuv -i6: .a.wlkhe hook o iikr.m 23xw+gafv* z0f a vertical spring scale, and then is release 2.g*zmfxrwii 3k+a0 vd. Describe the scale reading as a function of time.
参考答案: The scale reading will oscillate with damped oscillations about an equilibrium reading of 5.0 kg, with an initial amplitude of 5.0 kg (so the range of readings is initially from 0.0 kg and 10.0 kg). Due to friction in the spring and scale mechanism, the oscillation amplitude will decrease over time, eventually coming to rest at the 5.0 kg mark.
