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
Homework Answers
In first case, acceleration is zero as the velocity is constant,
in other two cases we have used FBDs and force equation to reach
answer
