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 vf, undergoing displacement s given by s= f Mi. 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. 15 W = Submit Request Answer ?
