Answer:
1000 N
Explanation: As car is moving with constant velocity , so acceleration of the car is zero. Then net force is equal to zero.Thus the applied force by car is equal and opposite to the frictional force.
f - ma = lmg
Where, l is coefficient of friction
f force applied by car
a is the acceleration of the car which is zero
m mass of the car
lmg = f = 1000 N = friction force

Answer:
the car is moving with constant velocity, this means acceleration =0
F=MA=0
Force = friction =1000N
