K constant= 347.454
Now, three masses m1 = 3.9 kg, m2 = 11.7 kg and m3 = 7.8 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above.
Now the elevator is moving downward with a velocity of v = -2 m/s but accelerating upward with an acceleration of a = 5.2 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?

I think I may be able to solve this question if I could figure out how to get a.
