- A small fly of mass 0.8 g is caught in a spider's web. The web oscillates predominantly with a frequency of 10 Hz. At what frequency (in Hz) would you expect the web to oscillate if an insect of mass 0.5 g were trapped? (What equation can I use to find the frequency at which it ocilates?)A weight of 32 lb stretches a spring 6ft. The weight is pulled down 2ft below the equilibrium position and then released. What initial velocity v0 given to the weight would have the effect of doubling the amplitude of the vibration? Use g=32 ft/sec 2. (Type an exact answer, using radicals as needed.)Which of the following mass-spring systems will have the highest frequency of vibration? Case A: A spring with a k=300 N/m and a mass of 200 g suspended from it.Case B: A spring with a k=400 N/m and a mass of 200 g suspended from it.
