A 2-kg object oscillates on a spring of force con- stant k = 400 N/m. The damping constant has a value of b = 2.00 kg/s. The system is driven by a sinusoidal force of maxi- mum value 10 N and angular frequency w = 10 rad/s. (a) What is the amplitude of the oscillations? (b) If the driving frequency is varied, at what frequency will resonance occur? (c) What is the amplitude of oscillation at resonance?
