Calculate work done in moving the object...

Calculate work done in moving the object from `x=2` to `x=3m ` from the graph shown here.

Text Solution

Verified by Experts

From the graph , figure,
At `x=2m F=40N` and at `x=3m, F=60N`
Work done ` =` Area enclosed by F-x graph

`=(1)/(2)(40+60)xx(3-2)=50 J`
