Transcribed Image Text:A mass of 3 kg stretches a spring 6 cm. The mass is acted on by an external force of 10 sin() N (newtons) and moves in a medium that imparts a viscous force of 4 N when the
speed of the mass is 2 cm/s. If the mass is set in motion from its equilibrium position with an initial velocity of 9 cm/s, formulate the initial value problem describing the motion of the
mass. (Use g = 9.8 m/s2 for the acceleration due to gravity. Let u(t), measured positive downward, denote the displacement in meters the mass from its equilibrium position at time
t seconds. Use up for u' and upp for u".)
