Now, three masses m1 = 3.1 kg, m2 = 9.3 kg and m3 = 6.2 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above.(k=253.16) the elevator is moving downward with a velocity of v = -2.8 m/s and also accelerating downward at an acceleration of a = -3.0 m/s2. What is the distance the MIDDLE spring is extended from its unstretched length? What is the distance the TOP spring is extended from its unstretched length?
