A 10 kg object is attached to a spring and will stretch the spring 49 cm by itself. A forcing function of the form F(t) = 12 cos(wt) is attached to the object and the system experiences resonance. The object is initially displaced 7.5 cm downward from its equilibrium position and given a velocity of 9 cm/sec upward. Assume there is no damping in the system and displacement and velocity are positive downward. Use g = 9.8 m/s².
