Answer #1

Where = 2f = 2*0.52 and k1= 495N/m and k2 = 990N/m and find the mass,

2*0.52 = 495+990/m

m = 139.11kg.

I hope you understood the problem and got your answers, If yes rate me!! or else comment for a better solutions

(1A) A vertical spring with a spring constant of 8 N/m and damping constant of 0.05 kg/s has a 2 kg mass suspended from it. A harmonic driving force given by F = 2 cos(1.5 t ) is applied to the mass. What is the natural angular frequency of oscillation of the mass? What is the amplitude of the oscillations at steady state? Does this amplitude decrease with time due to the damping? Why or why not? (1B) Two traveling...
