a fisherman's scale stretches 3.6 cm when a 2.7 kg fish hangs from it.
what will be the amplitude and frequency of vibration if the fish is pulled down 2.5 cm more and released so that it vibrates up and down?
i think the frequency is 2.63 Hz, but i don't know how to find the amplitude
THe amplitude will be the initial deviation from the rest position, given as 2.5cm
