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?
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|
