Question
Transcribed Image Text:A 3 kg object is attached to a spring and will stretch the spring 29.4 cm by itself. A
forcing function of the form F(t) = 10 cos(wt) is attached to the object and the
system experiences resonance. The object is initially displaced 14.5 cm downward from
its equilibrium position and given a velocity of 7 cm/sec upward. Assume there is no
damping in the system and displacement and velocity are positive downward. Use
g 9.8 m/s². Keep the coefficients in your answer exact or round them off to at least
five decimal places.
