just friction and air resistance. so the net force would be in the opposite direction to motion?

so there would also be frictional force as well as air resistance. but surely not thrust because the engine is off in the other directions, there would be weight and normal contact force

the only force would be air resistance? so would the net force be the force due to air resistance only and, therefore, it decelerates to a stop?
