Equations of Simple Harmonic Motion (basic)
PLEASE! show work and only answer if you know how to do it.
People keeps giving me the wrong answer.
Analyzing Newton's 2^nd Law for a mass spring system, we found a_x = -k/m X. Comparing this to the x-component of uniform circular motion, we found as a possible solution for the above equation: x = Acos(omega t) v_x = - omega Asin(omega t) a_x = - omega^2 Acos(omega t) with omega = square...

For the vibration absorber model below. (a) ma is selected to be 5% of main mass m, what should the value of ka be so the vibration of the main mass is eliminated? (b) What are the natural frequencies of the system? (c) Adding a damper to the absorber such that the absorber has a damping ratio of 0.5, how much would the main mass vibrate now? What if the excitation frequency...

6. A playground merry-go-round, i.e., a horizontal disc of radius 3 m that can rotate about a vertical axis through its center, is rotating at an angular speed 1/s (measured, as usual, in terms of radians). The moment of inertia of the merry-go-round with respect to that axis is 3000 kg m? A student of mass 80 kg is standing at the center of the merry-go-round. The student now walks outward...
