Question: A 2-kg object oscillates on a spring of force constant k = 400 N/m. The damping constant has a value of b = 2.00 kg/s.

A 2-kg object oscillates on a spring of force constant 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 maximum 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?

(d) What is the width of the resonance curve ∆w?
