Answer:
Power that must be put into the system for an applied force, F, to keep the rail in motion at constant speed, v,
= (Fapplied) × (constant speed of the rail)
P = Fv
Explanation:
The question is incomplete; but the solution to this is straight forward.
The power required to be put into the system for an applied force, F, to keep a rail/body/object in motion at a constant speed of v, is given as
Power = (Fapplied) × (The constant speed)
P = Fv
