1.

. A force F acting on an object varies with distance x asshown in figure. The work done by the force in movingthe object from x = 0 to x=20 m is10075+505 10 15 20

Answer»

Work done is given by the area under F-x curve.

W = (100N*10m) + {0.5*100N*(20-10)m} = (1000 +500) joules = 1500 joules. Ans
