We have a combination of two springs and two blocks as shown in the figure. The top spring has a spring constant k1 = 114r Wm and mass of the top block is m1 = 1.6 kg and the bottom spring has a spring constant k2 = 476 Mm and mass of the lower block is m2 = 2.5 kg. The elevator is moving up with an acceleration ofa = 2.4 mr'si's. 25% Part (a) What is the extension of the bottom spring in meters? 3L2 = 0.3 xAttempts Remain 25% Part (b) What is the extension of the top spring in meters? 25% Part (c) What is the extension of the bottom spring be in meters if the elevator is moving down with the same acceleration instead of upwards? 25% Part (d) What is the extension of the top spring be in meters if the elevator is moving down with the same acceleration instead of upwards
