A car whose mass is 1000kg is traveling at a constant speed of 10 m/s2. Neglecting any friction, how much force will the engine have to supply to keep going the same speed?

Without friction, NO FORCE is required to keep a moving object moving
at a constant speed in a straight line. 

Force CHANGES speed or direction.  If neither speed nor direction changes,
then there's no force acting on the object.
