a car is intended to move on a rough road by applying a force of 1000 N. Calculate the force of friction if the car starts moving with a constant velocity of 30 km/h on the rough road.
you can take ur time but plz answer it properly......

Answer:
1000 N
Explanation:
As the car is moving with constant velocity, so the 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 the 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
