Question
as part of an attempt to combine physics and biology in the same class, an instructor asks students to weigh a 5.0 kg salmon by hanging it from a fish scale attached to the ceiling of an elevator. what is the apparent weight of the salmon if the elevator a) is at rest, b) moves with an upward acceleration of 2.5 m/s^2, or c) moves with a downward acceleration of 3.2 m/s^2? as part of an attempt to combine physics and biology in the same class, an instructor asks students to weigh a 5.0 kg salmon by hanging it from a fish scale attached to the ceiling of an elevator. what is the apparent weight of the salmon if the elevator a) is at rest, b) moves with an upward acceleration of 2.5 m/s^2, or c) moves with a downward acceleration of 3.2 m/s^2? as part of an attempt to combine physics and biology in the same class, an instructor asks students to weigh a 5.0 kg salmon by hanging it from a fish scale attached to the ceiling of an elevator. what is the apparent weight of the salmon if the elevator a) is at rest, b) moves with an upward acceleration of 2.5 m/s^2, or c) moves with a downward acceleration of 3.2 m/s^2?Explanation / Answer
aO at rest = mg = 5(9.8) = 49 N
b( upward accleration = 5 ( 9.8 + 2.5) = 122.5 N
c) ( dowanward acceleration) = 5 ( 9.8 -3.2.) = 33N
