A car of mass 500kg is travelling along a flat road. its engine provides a forward force of 300N. Air resistance is 200N. What will its acceleration be?

(300-200) = 500a

To find the acceleration of the car, we need to use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula for calculating acceleration is:

acceleration = net force / mass

In this case, the net force acting on the car is the difference between the forward force provided by the engine and the air resistance.

Net force = forward force - air resistance

Plugging in the values given:

Net force = 300N - 200N = 100N

Now we can calculate the acceleration:

mass = 500kg
net force = 100N

acceleration = 100N / 500kg = 0.2 m/s²

Therefore, the acceleration of the car is 0.2 m/s².
