The mechanical system shown in the figure is
acted upon by two forces u1 and u2 that are
applied at the same time when the system was at
rest. Knowing that the system is under the effect of
gravity g and that the displacements d1 and d2 of
the masses m1 and m2, as well as the velocities v1
and v2 of said masses are measured from the rest
position, find the equation of states corresponding
to speed v2. Consider that the viscous damping
coefficient is b1 = 10 N s / m, that the mass of the
bodies is m1 = 1 kg and m2 = 5 kg, and that the
spring constant of elasticity is k1 = 2 N / m and k2 =
5 N/m.
