A 69.0 kg person weighs themself by standing on a scale in an elevator. (a) What does the scale read (in newtons) when the elevator is descending at a constant speed of 9.00 m/s? (b) What does the scale read (in newtons) if the elevator is accelerating downward with an acceleration of 3.00 m/s2? (c) If the elevator's descending speed is measured at 9.00 m/s at a given point, but its speed is decreasing by 3.00 m/s2, what does the scale read (in newtons)?
