An elevator cabin has a mass of $363.7 \mathrm{~kg},$ and the combined mass of the people inside the cabin is $177.0 \mathrm{~kg} .$ The cabin is pulled upward by a cable, in which there is a tension force of $7638 \mathrm{~N}$. What is the acceleration of the elevator?

Key Concepts

Newton's Second Law

This principle states that the net force acting on an object is equal to the product of its mass and acceleration (F_net = ma). It is fundamental for analyzing the motion of objects when subjected to various forces and is used to determine acceleration when the net force and total mass are known.

Gravitational Force

Gravitational force is the force exerted by the Earth on an object, calculated as the product of mass and the acceleration due to gravity (mg). This force acts downward and must be overcome by any upward force, such as tension, to achieve upward acceleration.

Tension Force

Tension is the force transmitted through a cable or rope when it is pulled tight by forces acting from opposite ends. In problems involving elevators, the tension in the cable provides the upward force that combats the gravitational force acting on the combined mass of the elevator and its contents.

Net Force Calculation

The net force is determined by subtracting the downward gravitational force from the upward tension force. This net force is then used in Newton's second law (F_net = ma) to calculate the acceleration of the system.

Free-Body Diagram

A free-body diagram is a simplified representation of an object that shows all the external forces acting upon it. In the context of the elevator problem, it helps visualize the upward tension force and the downward weight, making it easier to set up the equations needed to solve for acceleration.
