Answer

a. 0.14 N/m b. 2.8 Hz

Work Step by Step

a. Use equation 11-6b to relate frequency, mass, and spring constant. $$f=\frac{1}{2 \pi}\sqrt{\frac{k}{m}}$$ $$k=4 \pi^2f^2m=4 \pi^2(4.0Hz)^2(2.2 \times 10^{-4}kg)=0.1390 N/m \approx 0.14 N/m$$ b. $$f=\frac{1}{2 \pi}\sqrt{\frac{0.1390 N/m}{4.4 \times 10^{-4}kg }}\approx 2.8 Hz$$
