You are standing in an elevator as it begins to accelerate downwards at 1.5 m/s^2. a) Sketch a force identification diagram, including all the forces acting on you inside the elevator. b) Sketch a free body diagram including the direction of the forces and properties of the motion you experience. c) Sum the forces acting on you and use Newton's second law to help calculate your apparent weight (which results from the change in the contact force that you experience as you accelerate).

Whenever you face a problem involving forces, always start with a free-body diagram.
Learning Goal: To gain practice drawing free-body diagramsWhenever you face a problem involving forces, always start with a free-body diagram.To draw a free-body diagram use the following steps:Isolate the object of interest. It is customary to represent the object of interest as a point in your diagram.Identify all the forces acting on the object and their directions. Do not include forces acting on other objects in the problem. Also, do not include quantities, such as velocities and accelerations, that do...

A large fish hangs from a spring balance supported from the roof of an elevator. If the elevator has an upward acceleration of 2.45 m/s2 and the balance reads 60.0 N , what is the true weight of the fish? SET UP Draw a sketch of the physical situation, and identify the moving object or objects to which you will apply Newton’s 2nd law. Draw a free-body diagram for each chosen object, showing all the forces acting on that object....

Problem 1: A 1000.0 kg elevator is controlled with a cable. Friction and air resistance can be ignored. In this problem, the elevator is already moving downward at a constant speed of 1.0 m/s. During this initial stage, the elevator moves with this constant speed for 1.5 seconds. Then, in a 2nd stage, the elevator slows down to a stop with constant acceleration. During this 2nd stage, it takes 0.5 seconds of time to come to a stop. A. Draw...
