Substitute for f from part b in the expression for work from part c. then substitute for a from the relation in part a. this will yield an expression for the net work w done on the particle by the external forces during the particle's motion in terms of mass and the initial and final velocities. give an expression for the work w in terms of those quantities. express your answer in terms of m, vi, and vf.
