A 685-kg elevator starts from rest and moves upward for 2.70 s by constant acceleration until it reaches its cruising speed, 1.75 m/s.
a) What is the average power of the elevator motor through this period?
b) How does this amount of power compare with its power through an upright trip by constant speed?
