Frequency of an oscillating spring:
From Hooke's law:
x = 10.0 cm(1m/100cm) = 0.1 m
F = 245 N
k = F/x = 245/0.1 = 2450 N/m
The scale of a spring balance reading from 0 to 245N has a length of 10.0cm. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.20Hz.
Ignoring the mass of the spring, what is the mass (m) of the fish?
