Find the acceleration a of the particle express the acceleration in terms of v, vf, and s. learning goal: to understand the meaning and possible applications of the work-energy theorem in this problem, you will use your prior knowledge to derive one of the most important relationships in mechanics: the work-energy theorem. we will start with a special case: a particle of mass m moving in the x direction at constant acceleration a during a certain interval of time, the particle accelerates from vi to ve, undergoing displacement s given by view available hint(s) 2s answer requested part b find the net force f acting on the particle. express your answer in terms of m and a. view available hintfs) f- mo correct part c find the net work w done on the particle by the external forces during the particle's motion express your answer in terms of f and s.
