If a car is moving to the left with constantvelocity, one can conclude thatthere mustbe no forces applied to the car. the netforce applied to the car is directed to the left. the netforce applied to the car is zero. there is exactly one force applied to the car.

Net Force is zero

Explanation:

Given

Car is moving to the left with constant velocity i.e. net force on the car is zero

because change in velocity with respect to time is acceleration thus  force is also zero because net acceleration is zero

Mathematically

acceleration

as velocity is constant therefore

thus a=0 , F=0
