Question
Give the magnitude and direction of the net force acting on. A car moving with a constant velocity of 30km/h on a rough road.

Answer

Force is being applied to overcome the force of friction. But as velocity of the car is constant, its acceleration, a = 0. Hence net force on the car F = ma = 0.
