1. The problem statement, all variables and given/known data How to prove : ##P*F_net=((dK)/(dt))## i.e. power associated with the net force is the rate of change of kinetic energy. 3. The attempt at a solution if I use the definition of power ans then that of work I get (m*a*ΔS )*(F_net) further using F_net=ma LHS= ##m^2*a^2*ΔS## There is no question along with it for which I could have though about the system and forces. so I am assuming const force and acceleration.
