In the second configuration, three masses m = m2 = 3.30 kg, 9.90 kg, and m3 = 6.60 kg hang from three identical, massless springs in a motionless elevator. The springs are identical to the spring in the first configuration. O Macmillan Learning For the three-mass configuration, the elevator moves downward with a speed of 3.10 m/s, but accelerates upwards with an acceleration of 5.10 m/s. What distance y does the upper spring extend from its unstretched length? Enter your answer in centimeters. 116 y = cm m1 Incorrect
