Question

Now, three masses m1 = 3.2 kg, m2 = 9.6 kg and m3 = 6.4 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above. 1-What is the distance the lower spring is stretched from its equilibrium length? 2-Now the elevator is moving downward with a velocity of v = -3.9 m/s but accelerating upward with an acceleration of a = 4.3 m/s2. (Note: an upward acceleration when the elevator is moving down means the elevator is slowing down.) What is the force the bottom spring exerts on the bottom mass? 3-What is the distance the upper spring is extended from its unstretched length?

Explanation / Answer

"""The springs all have the same spring constant that you just calculated above """ .... does this sentence is meaning ful i think may K or expansion must be given sorry unable to solve
