A person weighing 490 N (mass of 50 kg) stands on a scale in an elevator...
a: what is the scale reading in newtons when the elevator is at rest?
b: The elevator starts to ascend and accelerates the person upward at 2.2 m/s^2.
What does the scale read now?
c: What is the reading on the scale when the elevator rises at a constant velocity?
d: The elevator begins to slow down as it reaches the top floor.
Do the scale readings increase or decrease?
e: The elevator now starts to descend back to the ground.
Does the scale reading increase or decrease as the elevator accelerates down?
f: The elevator then decelerates and stops at the ground.
Does the scale reading increase or decrease as the elevator is decelerating to a stop.
g: If the cable snapped and the elevator fell freely, what would the scale reading be?
h: After the elevator has begun to decends, the scale reads 400 N.
At this point, what is the acceleration of the elevator?
