What net force is required to accelerate a car at a rate of 2 ms2 if the car has a mass of 3000kg?

The net force required to accelerate the car at a rate of 2 m/s^2 is 6000 N. This is calculated using Newton's second law, F = ma, where F is the force, m is the mass of the car (3000 kg), and a is the acceleration (2 m/s^2). So, F = 3000 kg * 2 m/s^2 = 6000 N.
