Question 6 (Unit 10) 5 marks Consider a particle that moves according to the equation of motion 5+20+16x10 cos(t), where is a constant. (a) Suppose that = 4. Calculate the amplitude of the resulting oscillations of the particle after a long time has elapsed. [2] (b) Calculate the damping ratio for this mechanical system to two decimal places, and hence state whether the particle can undergo resonance. [3]
