Question

If a 100N weight sits in an express elevator what will be the weight when the elevator is traveling at a constant speed

Answer 1

This is a "trick" question.

If the elevator is traveling at constant speed, it means it is at rest. This means anything inside the elevator traveling at constant speed, weights the same as in an elevator not moving -also at rest-.

So the 100N weight's weight doesn't change in an elevator traveling at constant speed.
