A car of mass 800 kg is moving with a constant velocity 40 km/h . Find the net force on it.

Explanation

To find the net force acting on a car of mass 800 kg moving with a constant velocity of 40 km/h, we can follow these steps:

### Step 1: Understand the motion of the car
The car is moving with a constant velocity of 40 km/h. This indicates that there is no change in speed or direction.

### Step 2: Identify the acceleration
Since the car is moving at a constant velocity, the acceleration of the car is zero. According to Newton's first law of motion, if an object is moving with a constant velocity, the net force acting on it must be zero.
