Problem: A 636-kg elevator starts from rest and moves upward for 2.60 s with constant acceleration until it reaches its cruising speed, 1.75 m/s.
Part A: What is the average power of the elevator motor during this period?
W
PArt B: How does this amount of power compare with its power during an upright trip with constant speed?
I want help to find the average power of the elevator motor during this period.
