1) What is the work done between 0 m and 4 m? 2) What is the work done be What is the definition of force? With what force must an electric motor accelerate an elevator with a mass of 1200 from 1 \ m/s to 5 \ m/s over a distance of 9 \ m? Give an example of a ...
Does the force exerted on you by the elevator do positive or negative work when the elevator (a) goes up and (b) goes down? Explain your answers. Say you ascend at a constant speed. You're right that 0 total work is done on you for most of the ride, because the work done ...

What force is needed to raise a 1200 kg elevator with an acceleration of 4 m/s^{2}? (Also, show a free-body diagram as part of your work). Find the work done by a force F = 8i - 6j + 9k that moves an object from the point (0, 10, 8) to the po...
Mechanical work is the type of work most commonly dealt with inphysicsandchemistry. It includes work moving against gravity (e.g., up an elevator) or any opposing force. Work is equal to the force times the distance the object moves: ...
