when two parallel springs with constants k1 and k2 support a single mass, the effective spring constant of the system is given by k 4k1k2/(k1 + k2). A mass weighing 20 pounds stretches one spring 6 inches and another spring 2 inches. The springs are first attached to a common rigid support and then to a metal plate. As the figure illustrates (see image), the mass is attached to the center of the plate in the distribution double spring. Determine the constant of the effective spring for this system. find the equation of motion if the mass is initially released from equilibrium position with downward speed of 2 ft/sec.

Question
Under some circumstances, when two parallel springs
with constants k1 and k2 support a single mass, the
effective spring constant of the system is given by
k 4k1k2/(k1 + k2). A mass weighing 20 pounds stretches
one spring 6 inches and another spring 2 inches. The
springs are first attached to a common rigid support
and then to a metal plate. As the figure illustrates
(see image), the mass is attached to the center of the plate in the distribution
double spring. Determine the constant of the
effective spring for this system. find the equation
of motion if the mass is initially released from
equilibrium position with downward speed of
2 ft/sec.
