A gardener pushes a lawn roller through a distance of 100m with a force of 50N . Calculate the wages if he is to be paid Re:1 for

25 J of work It is given that the applied force is inclined 60oto the direction of motion .

Work done=f×s cosθθ is the angle between direction of force and distance.Work done=50×100 cos60°=5000×12 =2500J for 25J of work he get 1rupee for 2500J of work he will get =250025=Rs100
