Answer: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
