A 3-kg object is attached to a spring with force constant 25 N/m and is driven by an external oscillator that provides a force given by the function F(t) = 4.6 sin(2 t), where F is force in newtons and t is time in seconds. Air resistance on the oscillating mass is represented by a damping coefficient of 1.9 N-s/m. a. Determine the natural angular frequency (aka the resonance angular frequency) of the system. rad/s or s-1 Wo= b. Determine the angular frequency of the driven system (from the given sinusoidal model). Express your answer as a decimal. rad/s or s-1 W= c. Determine the amplitude of the oscillation. A = cm
