Three masses m1 = 3.5 kg, m2 = 10.5 kg and m3 = 7 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant of 228.9 N/m. the elevator is moving downward with a velocity of v = -2.7 m/s but accelerating upward with an acceleration of a = 5.4 m/s^2. Find the distance of the upper spring extended from its unstretched length and the force the bottom spring exerts on the bottom mass.
