You are standing on a scale in an elevator. While the elevator is at rest, the scale reads 650 N.
The elevator begins to move with a downward velocity. If the elevator is increasing in speed
(speeding up), what will happen to the weight reading displayed by the scale?
The scale will measure a weight equal to 650 N
O The scale will measure a weight greater than 650 N
O The scale will measure a weight exactly equal to 0 N
The scale will measure a weight less than 650 N
A passenger is standing on a scale in an elevator. The building has a height of 500 feet, the passenger has a
mass of 80 kg, and the scale has a mass of 7 kg. The scale sits on the
oor of the elevator. You may take g
= 10 N/kg. While it is accelerating downwards hat does the scale read (in newtons
Fernanda is standing on a scale while riding an elevator. The elevator accelerates upward from rest to 1.8m/s1.8m/s in 2.0 s. If the scale reads 720 N while the elevator is accelerating upwards, what is Fernanda’s mass?
