 Homework Statement:
 It is not actually a homework
 Relevant Equations:

F.V=P
Fnet=ma
An elevator of mass M is accelerating downward with constant acceleration A. Friction force acting on the elevator is constant and given by f (The initial speed of the elevator is zero.). Find the power generated by the engine of the elevator (in terms of M, A, g, f, and time t).
For this question I write this equation Fnet.v=P and Fnet=mgmaf but there is time in my question and I think I couldn't use the velocity in an appropriate way.I know that work is equals to change in kinetic energy but I am not sure how can I write an equation which involves both v and t.If you have any idea,please share with me
