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...

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 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?
A 140 lb person rides in elevator while standing on a scale that reads in slugs. For each part below, draw a free body diagram, write the equations for Newton’s second law and solve. a.) If the elevator accelerates upward at 2.53 ft/s^2, what is the reading on the scale? b.) If the elevator accelerates downward at 1.53 ft/s^2, what is the reading on the scale? c.) If the elevator moves upward at a constant velocity of 2.53 ft/s, what...
2) A 60.0-kg person rides in elevator while standing on a scale. The elevator is traveling downward but slowing down at a rate of 2.00 m/s2. The reading on the scale is closest to A) 589 N. B) 708 N. C) 469 N. D) 120 N.
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
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...
