A 2.10-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 3.20sin(2πt), where F is in newtons and t is in seconds. The force constant of the spring is 22.0 N/m.
(a) Find the resonance angular frequency of the system.
(b) Find the angular frequency of the driven system.
(c) Find the amplitude of the motion.
