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 73.0-kg person stands on a scale in an elevator. What does the scale read (in N) when the elevator is at rest? What does the scale read (in N) when the elevator is climbing at a constant speed of 3.0 m/s? What does the scale read (in N) when the elevator is descending at 3.0 m/s? What does the scale read (in N) when the elevator is accelerating upward at 2.4 m/s2 ? What does the scale read (in...
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
