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 elevator is moving downward with a velocity of v = -2.3 m/s but accelerating upward with an acceleration of a = 4.8 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?

Question

anonymous · Answer

i'm not too sure but force=mass x acceleration. if you know gravity (9.8m/s^2) and you know acceleration (4.8) find the resultant acceleration and times it by the mass.|dw:1317130776669:dw|
