An escalator is used to move 20 passengers every minute from the first floor of a department
store to the second. the second floor is located 5.20 meters above the first floor. the average
passenger's mass is 54.9 kg. determine the power requirement of the escalator in order to
move this number of passengers in this amount of time.

W1 passenger = F • d • cos(0 deg)

W1 passenger = (54.9 kg • 9.8 m/s2) • 5.20 m = 2798 J (rounded)

W20 passengers = 55954 J (rounded)

P = W20 passengers / time = (55954 J) / (60 s)
