The work done by a force acting on a body is as shown in the graph. The total work done in covering an initial distance of 20 m is

Options:

Answer:

Solution:

Work done $W =$ Area $A BC D EFG A$ $=$ Area $A BC D G +$ Area $D EFG$ $= \frac{1}{2} \times (15 + 10) \times 10 + \frac{1}{2} \times (10 + 20) \times 5$ $= 125 + 75 = 200 J$
