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 stands on a weight scale in an elevator and pushes the button to go up. The elevator accelerates upward at 3 m/s2, then rises at a steady speed of 15 m/s, and finally decelerates at the top floor at a rate of 2 m/s2. Match the force values to their descriptions. Some values may be used more than once, and some may not be used at all. 1. person's weight during upward acceleration 2. scale reading during...
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 140-lb person is standing on a bathroom scale in an elevator as the elevator accelerates downward 1.2 m/s2 What does the bathroom scale read? Answer is 120 lbs. Please show step by step solution to this problem.
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 = ?
Draw a free-body diagram for a 70-kg person standing in an elevator carrying a 15-kg backpack (do not consider the backpack a part of the person!). (a) if the elevator is not moving, and (b) if the elevator is accelerating downwards at 2m/s2. In each case, what is the magnitude of the normal force exerted on the person by the floor?
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.
