Homework Answers
Total work done on an object = change in kinetic energy
Kinetic energy = 1/2 m v2.
In the given problem, velocity of elevator is constant. So, kinetic energy of the elevator does not change.
Hence, work done = change in kinetic energy of the elevator = 0 J.(option A)

A 68-kg man stands on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.2 m/s in 0.77 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.8 s, and then comes to rest. (a) What does the spring scale register before the elevator starts to move? N (b) What does the spring scale register during the first 0.77 s of the elevator's ascent?...

An elevator car with a mass of equal to 800 kg is pulled upward at constant speed. If the elevator moves a distance of 5m, how much work was done by the cable which pulls upward on the elevalor through that distance. 12 vg40000 The cable does no work, because there is no change in kinetic energy B. The cable does 40,000 J of work, because it must be equal to gain in potential energy The cable does more than...

An elevator has mass 600 kg, not including passengers. The elevator is designed to ascend, at constant speed, a vertical distance of 20.0 m (five floors) in 16.0 s, and it is driven by a motor that can provide up to 40 hp to the elevator. A. What is the maximum number of passengers that can ride in the elevator? Assume that an average passenger has mass 65.0 kg.
