A 1.90-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 2.80sin(2pt), where F is in newtonsand t is in seconds. The force constant of the spring is 38.0 N/m.
(a) Find the resonance angular frequency of the system.
——- s-1

(b) Find the angular frequency of the driven system.
