Question: A 1 . 8 0 - kg object attached to a spring moves without friction ( b = 0 ) and is driven by an

A 1.80-kg object attached to a spring moves without friction (b =0) and is driven by an external force given by the expression F =4.50sin(2(pi)t), where F is in newtons and t is in seconds. The force constant of the spring is 23.0 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.
