A particle moves along a straight path through displacement i = (2.2 m) + c while force = (3.2 N)  (3.8 N) acts on it. (Other forces also act on the particle.) What is the value of c if the work done by on the particle is (a) zero, (b) 3.2 J, and (c) 7.3 J?

I assume you have vector displacement andforces.
work=force dot displacement=3.2*2.23.8*c
solve for c.I will do one. If work 7.3J
7.3=7.043.8c
.26=3.8c
c=14.6
