if there is no friction, pulling at a steady speed on a level road does not do work.
If there is kinetic friction μk, then
F=force = μk * mg
v=velocity = 10 m/s
Power = F.v j/s = F.v watts

Steady speed means zero acceleration.
Since power=force*velocity and force is zero due to steady speed then power will also be zero.
In other words; power=force*velocity
Power=mass*acceleration *velocity
Since acceleration is zero.
Power=mass*0*velocity
Power=0hp OR 0watts
