You are standing on a bathroom scale inside an elevator. Your weight (as measured on a bathroom scale under ordinary conditions) is 168.3 lb, but reading on the scale is 146.5 lb. What is the y-component of the acceleration?
Homework Answers
consider the force on the scale
N - W = m a
where
- N = 146.5 lb-f
- W = 168.3 lb-f
- m = W / g = ( 168.3 lb ) / ( 32,17 ft/s² ) = 5.232 lb
then
a = ( 146.5 lb-f - 168.3 lb-f ) / ( 5.232 lb )
a = -4.167 ft/s²

You are standing on a bathroom scale and you measure the weight to be 120 lb. You then take the scale onto an elevator and stand on the scale as the elevator accelerates, during which the reading on the scale decreases to 90 lb. Which of the following statements about the elevator could be true? A. The elevator is moving upward at 2 m/s while accelerating downward at 2.45 m/s^2. B. The elevator is moving downward at 4 m/s while...

Suppose Arturo is standing on a spring bathroom scale in an elevator, which is at rest,...
Suppose Arturo is standing on a spring bathroom scale in an elevator, which is at rest, on the 15th floor. What is his acceleration? What forces are acting on him? What is the reading (in Newtons) on the bathroom scale if he has a mass of 150 kg? (Draw it out and Label it) Now imagine disaster - the rope holding the elevator snaps, there are no safety features, and the elevator plunges down the shaft in free fall. Herrera...

As part of a physics experiment, you stand on a bathroom scale in an elevator. Though your normal weight is 630 N , the scale at the moment reads 710 N . Part A Is the acceleration of the elevator upward, downward, or zero? Part B Explain Part C Calculate the magnitude of the elevator's acceleration. Express your answer using two significant figures. Part D What, if anything, can you say about the velocity of the elevator? Explain.

A person who normally weighs 250 pounds is standing on a scale inside an elevator. The elevator is moving upward with a speed of 7 m/s and then begins to decelerate at a rate of 5 m/s2(0.5 g). What is the reading on the scale before the elevator begins to decelerate? What is the reading on the scale during the deceleration?

You (mass = 75 kg) are riding in an elevator while standing on a scale. As the elevator begins to rise, you notice that the scale reading briefly increases to 785 N. What is the acceleration of the elevator during this time? Assuming it has three times the acceleration as it slows to rest at the top floor, what does the scale read as it slows?
