You stand on a spring scale on the floor of an elevator. Pick all the situations where the scale shows higher reading than your actual weight. A The elevator moves downward with increasing speed. B The elevator moves upward with decreasing speed. C The elevator moves downward with decreasing speed. D The elevator moves upward with increasing speed.

Problem. An elevator in a high - rise building is accelerating uniformly upward and then to a rest. The apparent weight of the rider is three times decelerating before coming greater during the acceleration than the deceleration. Find the acceleration of the elevator if its magnitude is the same throughout.

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...

Question 4 Part A Predict how the upward force exerted on the feet by the scale will compare to the weight of the man if the elevator is moving upward at a constant speed. The upward force on the feet will be equal to the man’s weight. The upward force on the feet will exceed the man’s weight. The upward force on the feet will be less than the man’s weight. Part B Predict how the upward force exerted on...

Suppose you are standing on a weighing scale in an elevator that accelerates downward with a magnitude of 9.8 m/s2. The reading of the scale a) is zero b) is less than when the elevator was st rest c) is greater than when the elevator was at rest d) is the same as when the elevator was at rest e) none of these

Question 5 Constant:s Part A You are riding in an elevator on the way to the 18th floor of your dormitory. The elevator accelerationg upward with a 1.90 m/s . Beside you is the box containing your new computer; box and contents have a total mass of 35.0 kg. While the elevator is accelerating upward, you push horizontally on the box to slide it at constant speed toward the elevator door. If the coefficient of kinetic friction between the box...

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.

An object is hanging by a string from the ceiling of an elevator. The elevator is moving upward with a constant speed. What is the magnitude of the tension in the string? The magnitude of the tension in the string is equal to the magnitude of the weight of the object. The magnitude of the tension in the string is less than the magnitude of the weight of the object. The tension in the string cannot be determined without knowing...

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?
