Question
Find the acute angle that a constant unit force vector makes with the positive $x$-axis if the work done by the force in moving a particle from $(0,0)$ to $(4,0)$ equals 2 .
Step 1
The work done by a constant force is given by the dot product of the force and the displacement. In this case, the force is a constant unit vector, so the work done is simply the dot product of the force and the displacement vector. Show more…
