    A person who normally weighs 250 pounds is standing on a scale inside an elevator. The elevator is moving upward with a speed of 7 m/s and then begins to decelerate at a rate of 5 m/s2(0.5 g). What is the reading on the scale before the elevator begins to decelerate? What is the reading on the scale during the deceleration?

    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 single mass (m1 = 4.4 kg) hangs from a spring in a motionless elevator.

    A single mass (m1 = 4.4 kg) hangs from a spring in a motionless elevator. The spring constant is k = 270 N/m. 1) What is the distance the spring is stretched from its unstretched length?  2) Now, three masses (m1 = 4.4 kg, m2 = 13.2 kg and m3 = 8.8) hang from three identical springs in a motionless elevator. The springs all have the same spring constant given above. What is the magnitude of the force the bottom spring exerts on the...

    You (mass = 75 kg) are riding in an elevator while standing on a scale. As the elevator begins to rise, you notice that the scale reading briefly increases to 785 N. What is the acceleration of the elevator during this time? Assuming it has three times the acceleration as it slows to rest at the top floor, what does the scale read as it slows?

    Consider a 77.0-kg man standing on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.08 m/s in 0.900 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.70 s and comes to rest. (a) What does the spring scale register before the elevator starts to move? N (b) What does the spring scale register during...
