In summary, the conversation discusses the problem of a 80.0 kg person standing on a scale in an elevator that is accelerating downward at 3.5 m/s2. The person is having trouble finding the correct answer using the formula EF = ma. They suggest showing working and thought processes for previous parts of the question to receive better help. Additionally, it is mentioned that when an elevator goes downwards, a person may feel lighter due to the modified acceleration of the elevator and gravity.

I'm having trouble with this problem:

A 80.0 kg person stands on a scale in an elevator.
(e) What does it read when the elevator is accelerating downward at 3.5 m/s2? In KG

I set it up as EF = ma , but it doesn't work out...

EF = MA

How did you get on with parts (a) to (d) of the question? It would probably be useful to show some working and thought processes for those parts of the question, then people will have a better idea of how to help.
 
  • #3
When an elevator goes downwards, you feel lighter. Note that all the person's weight normally comes from gravity acceleration. Find the modified acceleration of the elevator and gravity together, then compare that with just gravity.
 

FAQ: Avoiding Elevator Problems: Solving for Force and Acceleration in an Elevator

What is the "Elevator Problem"?

The "Elevator Problem" is a mathematical problem that involves finding the optimal way to program an elevator system in a building to efficiently transport passengers to their desired floors.

What factors are considered when solving the "Elevator Problem"?

Factors such as the number of floors in the building, the number of elevators, the capacity of each elevator, peak usage times, and the desired wait time for passengers are all considered when solving the "Elevator Problem".

What are some strategies for solving the "Elevator Problem"?

Some strategies for solving the "Elevator Problem" include grouping passengers by their desired floors, using algorithms to predict and anticipate passenger traffic, and implementing smart technology such as automatic destination selection.

What are the potential challenges in implementing solutions for the "Elevator Problem"?

Some potential challenges in implementing solutions for the "Elevator Problem" include cost constraints, technological limitations, and human error. It is also important to consider the safety and security of passengers while implementing new systems.

Why is it important to solve the "Elevator Problem"?

The "Elevator Problem" is important to solve because it can greatly improve the efficiency and convenience of elevator systems in buildings. This not only saves time for passengers, but also reduces energy consumption and maintenance costs for building owners. Additionally, solving the "Elevator Problem" can lead to advancements in smart technology and transportation systems in general.
