I'm stuck on this problem. It's one problem with multiple parts

A 1.70-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 5.50sin(2xt), where F is in newtons and t is in seconds. The force constant of the spring is 13.0 N/m. (a) Find the resonance angular frequency of the system. (b) Find the angular frequency of the driven system. s - 1 (c) Find the amplitude of the motion. cm Need Help? Read It
