Apps introduction to imp O 0110 points 1 Previous Amis SerPSE 10 A5 OP021 A Tour Tr A manufacturer uses an elevator to move items from one level to another. The elevator has a mass of 650 kg and moves upward with constant acceleration for 4.50 s until it reaches its cruising speed of 1.75 m/s. (Note: 1 hp 746 W.) (a) What is the average power (in hp) of the elevator motor during this time interval? P8777 x As the elevator accelerates upward, both the motor and gravity do work and the work-kinetic energy theorem informs us that the net work done a equal to the change in kinetic energy. We have sufficient information to determine the change in kinetic energy, the work done by gravity, and hence the work done by the motor. Knowing the work done by the matar end the time over which this work is done, we can determine the power supplied by the motor hp (b) What is the motor power (in hp) when the elevator moves at its cruising speed? hp (c) What If? If the elevator motor can only deliver constant power at one setting, the amount needed for its motion at constant speed, how long (in x) will it take the elevator in accelerate to the cruising speed of 1.75 m/s?
