Question

A vertical scale on a spring balance reads from 0 to 235 NN . The scale has a length of 10.0 cmcm from the 0 to 235 NN reading. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.30 HzHz . Part A Ignoring the mass of the spring, what is the mass mmm of the fish

    Answer:

    11.25 kg

    Explanation:

    We are given that

    Force,F=235 N

    Length,l=10 cm=10\times 10^{-2} m

    1m=100 cm

    Frequency,f=2.3Hz

    We have to find the mass m of the fish.

    Spring constant,k=\frac{F}{l}=\frac{235}{10\times 10^{-2}}=2350N/m

    Mass of the fish=m=\frac{k}{4\pi^2f^2}

    Substitute the values

    m=\frac{2350}{4\pi^2(2.3)^2}

    m=11.25 kg

    Hence, the mass of the fish=11.25 kg
