**drwls**, Friday, October 30, 2009 at 1:33pmTake the "dot product" of the force vector and the displacement vector. If i is the x unit vector and j is the y unit vector, the force vector is

F = 2.4 sin 100 i + 2.4 cos 100 j

The displacement vector is

deltaR = 3.0 i + 4.1 j

W = F . (deltaR)

= 7.2 sin 100 + 9.84 cos 100
