Question

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 9 n when the speed of the mass is 3 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.
