Question

The force on a particle is described by 4x^3 +2 at a point along the -axis. Find the work done in moving the particle from the origin to x=8.

Answer 1

Generally, work done = force x distance

if we are talking about force exerted at an angle to the direction of the movement, then it will be

WD= FxS (cos angle)
