container factory uses a 450 W motor to operate a conveyor belt that lifts containers from one
floor to another. To lift 250 1-kg containers a vertical distance of 2.4 m, the motor runs for 45 s.
What is the efficiency of the motorized conveyor system?

energy output= 250g*2.4
energy input= 450*45s

efficiency= output/input
