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.
When a 45-kg person steps on a scale in an elevator, the scale reads a steady 480 N. Which of the following statements must be true? (There could be more than one correct choice.) Check all that apply. The elevator is moving upward at a constant rate. The elevator is accelerating upward at a constant rate. The elevator is accelerating downward at a constant rate. From the given information, we cannot tell if the elevator is moving up or down.
Suppose a person with a mass of 60 kg is in an elevator standing on a scale that reads in Newtons. Use a free body diagrams of the scale and the person to determine what the scale would read for the following situations: A. If the elevator is descending at 4.9 m/s. B. If the elevator has a downward acceleration of 4.9 m/s2 . C. If the elevator has an upward acceleration of 4.9 m/s2 . explain WHY
A 96.5-kg person stands on a scale in an elevator. What is the apparent weight when the elevator is (a) accelerating upward with an acceleration of 1.57 m/s2, (b) moving upward at a constant speed, and (c) accelerating downward with an acceleration of 1.79 m/s2?
Henry, whose mass is 95 kg, stands on a bathroom scale in an elevator. The scale reads 830 N for the first 2.8 s after the elevator starts moving, then 930 N for the next 2.8 s. What is the elevator's speed 5.6 s after starting?
A 86.8-kg person stands on a scale in an elevator. What is the apparent weight when the elevator is (a) accelerating upward with an acceleration of 1.72 m/s2, (b) moving upward at a constant speed, and (c) accelerating downward with an acceleration of 1.67 m/s2? (a) Number Units (b) Number Units (c) Number Units
A 74.0 −kg person stands on a scale in an elevator. What does the scale read (in kg) when the elevator is accelerating upward at 3.2m/s^2? What does the scale read (in N) when the elevator is accelerating downward at 3.2m/s^2? What does the scale read (in kg) when the elevator is accelerating downward at 3.2m/s^2?
A person stands on a scale inside an elevator at rest and the scale reads 900 N. If the elevator moves upward at a constant speed of 3 m/s, what does the scale read then? What if the elevator accelerated upward at a constant rate of 3 m/s2, what does the scale read then? 900 N, 2700 N 900 N, 3600 N 900 N, 624.5 N 1175.5 N, 1175.5 N 900 N, 1175.5 N Flag this Question Question 282 pts...
A 75 kg person is standing on a scale in an elevator. What is the reading of the scale in newtons if the elevator is a) at rest b) moving up at a constant velocity of 2.00 m/s c) accelerating up at 2.00 m/s
_ elevator platform scale 30. Using the above picture, a 90 kg person stands on a scale in an elevator a) Calculate weight of the person on the scale if the elevator is stationary. b) Calculate the weight of the person on the scale if the elevator is moving at constant velocity upward. c) Calculate the apparent weight of the person on the scale if the elevator is accelerating upward at 2m/s d) Calculate the apparent weight of the person...
