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

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...
