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*2.2-3.8*c

    solve for c.I will do one. If work 7.3J

    7.3=7.04-3.8c
    .26=3.8c
    c=14.6
