Answer:
Given that, mass m = kg and reading on scale is 11 N
Now, the weight of the suitcase is W = mg = 10kg x 9.8 m/s2 = 98 N
The reading value 11 N is less than the weight 98 N, that means the elevator is accelerating down. Option (B).
a 10kg suitcase is placed on a scale that is in an elevator. if the scale...
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.
You are standing on a scale in an elevator initially at rest and the scale reads 71.2 kg. The elevator begins to ascend and accelerates at a rate of 3.57 m/s 2 . What would the scale read (in kg) when the elevator is moving upwards and accelerating?
V. ELEVATOR REVIEW A man stands on a scale in an elevator. The elevator moves downwards at a velocity of 10 m/s. The elevator accelerates “pwards at a rate of 5 m/s.. The scale under the man reads 180 lbs. A. Is the elevator slowing down or speeding up? B. Given that 1 pound 4.5 Newtons, compute the man's mass? HINT: normal force is not necessarily cqual to weight. You have to usc NII C. The elevator reaches a complete...
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
If a person steps on a scale in an elevator that is accelerating at a rate 1.300 m/s^2 (negative means downward while positive means upwards) and sees a scale reading of 660.400 Newtons what would the scale read if the elevator were not moving?
_ 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...
E. Suppose you are standing on the scale in the elevator and the elevator is accelerating downward with an acceleration smaller than 9.8 m/s2 i. Draw free-body diagrams of yourself, the scale, and the floor of the elevator where it interacts with the scale. ii. How must the magnitude of the force exerted by the scale on you compare with your own weight? iii. How must the reading on the scale compare with the reading you make when the elevator...
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?
if a person was standing on a scale in an elevator that is accelerating down with 1 m/s2 the reading on the scale is 4.5kg DURIN THE DECELERATION OF THE ELEVETOR What is the normal force? and what is the mass of the person, thanks
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?
