ID: 15616Nhận biết (M1) A mass weighted 1000 g stretches a spring 20 (cm). The mass is acted on by an external force of (N) and moves in a medium that imparts a viscous force of 2 (N) when the speed of the mass is 4 (cm/s). The mass is pulled down 3 (cm) from its equilibrium position and released. Formulate the initial value problem describing the motion of the mass and solve it. ()
