Calculate the work done for lifting one box. how much energy is transfered when one box is lifted.if the man liftes 4 boxes per min at what power is he working

Answer 1

Dear student

• Work done in lifting one box = F × d = 100 × 1.5 = 150 J

• Work = Energy = 150 J

• Power = Work done / Time = (150×4)/ 60=10W
