Question: A 645 kg elevator starts from rest. It moves upward for 3.27 s with constant acceleration until it reaches its cruising speed, 1.60 m/s.
Part A: What is the average power of the elevator motor during this period?
Part B: What is the power of the elevator motor during an upward cruise with a constant speed of 1.60 m/s?
I need help to find the average power of the elevator motor during this period.
