Question
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. Keep the coefficients in your answer exact or round them off to at least
five decimal places.
a) What is the differential equation of the motion?
y'' +
=
y' +
Y
b) Solve the differential equation to find the displacement as a function of time (t).
y(t)
