Average power of the elevator motor through this period

Reference no: EM13668527

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 with constant speed?
