Question

why do we use third equation of motion in proofing the kinetic energy theorem ?​

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

→If we were to plug in for F equals MA and somehow substitute all of this, we will eventually arrive at an equation called the Work Energy Theorem which says that work done equals change in kinetic energy. So work done equals final kinetic energy minus the initial kinetic energy.
