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?
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 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
A 30.7 kg box rests on the floor of an elevator. What is the normal force (in N) on the box if the elevator accelerates downward at 3.34 m/s2?
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 51 kg person standing on a scale in an elevator that is accelerating upwards at 2m/s2. What is the normal force acting on the person (i.e., what would the scale read)? FN = ?
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.
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
4 4. An 80-kg man stands in an elevator. What is his apparent weight when 1) the elevators stationary, IT) the elevator accelerates up at 2 m/s?. III) the elevator accelerates down at 2 m/s IV) the elevator cruises up at constant velocity of 1 m/s. A) Draw a free body diagram of the man labeling the two forces (n and weight) acting on him. B) Write Newton's 2nd law, just including the vertical components. C) Put the forces n...
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...
