A 650-kg elevator starts from rest. It moves upward for 3.00 s with constant acceleration until it reaches a cruising speed of 1.75 m/s.

(a) What is the average power of the elevator motor during this time interval?

(b) How does this power compare with the motor power when the elevator moves at its cruising speed?

The elevators in the Empire State Building travel the 101 stories of the structure in less than 1 minute. In doing so, they accelerate from rest for the first 5.00 s of the upward trip to reach their cruising speed of 6.10 m/s. An elevator full of passengers has a mass of 1155 kg. What is the average power of each elevator's motor during (a) the acceleration and (b) the cruising phase of its motion?

A 72-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 0.80 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.5 s, and then comes to rest. What does the spring scale register:

(a) Before the elevator starts to move?

(b) During the first 0.80 s of the elevator’s ascent?

(c) While the elevator is traveling at a constant speed?

(d) During the elevator’s negative acceleration?
