Question

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

Answer 1

Zero net force

The car is moving on a rough road with a constant velocity. Hence, its acceleration is zero. As per Newton’s second law of motion, no net force is acting on the car.

Answer 2

Since car is moving with a constant velocity, the net force on the car is zero.
