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.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
