While in an elevator, you decide to take some weight readings of yourself to determine the elevator’s acceleration. When the elevator is stopped, you read a weight of 58.8 kg. When the elevator is moving, you measure a maximum weight of 62.4 kg, and a minimum weight of 57.9 kg.
(a) What is the maximum upward acceleration of the elevator?
(b) What is the maximum downward acceleration of the elevator?

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...

You walk into an elevator, step onto a scale, and push the "up" button. You recall that your normal weight is 621 N . When the elevator has an upward acceleration of magnitude 2.70 m/s2 , what does the scale read? (792 N) If you hold a 3.81-kg package by a light vertical string, what will be the tension in this string when the elevator accelerates as in the previous part?

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?

Assume that while ascending, an elevator has the same magnitude of acceleration "a" during starting (accelerating) and stopping (decelerating). A person stands on a scale in that elevator, and hence pushes downwards on the scale. The scale also reacts with an upward normal force. The maximum and minimum scale readings are Nace = 600 N and N dec = 400 N, respectively. acceleration of...
