Question

2. A force F=-K(vi+xj) (where K is a positive constant)
acts on a particle moving in the x-y plane. Starting from
the origin, the particle is taken along the positive .r-axis
to the point (a, 0) and then parallel to the y-axis to the
point (a, a). The total work done by the forces F on the
particle is
