A force F = (4.0 N)i + cj acts on a particle as the particle goes through displacement d = (3.4 m)i  (2.0 m)j. (Other forces also act on the particle.) What is the value of c if the work done on the particle by force F is each of the following?
(a) zero
(b) 19 J
(c) 17 J
Work is the dot product of the Force and Dispacement vectors.
Set W = 13.6  2c and solve for the c that goes with each W.
(13.6 2c is the dot product.)
Thanks! You're awesome :)
