A force F=a+bx acts on a particle in the x-direction where a and b are constants. Find the work done by this force during a displacement from x=0 to x=d.
Given that, F = a+bx
Where a and b are constants,
So, work done by this force during the
displacement x=0 to x=d is given by,
W=∫d0Fdx
=∫d0(a+bx)dx
=[ax+bx22]d0
=ad+bd22
