Ответ:
Net force required to accelerate the car is 6000 N
Explanation:
Force is calculated by the equation, F = Mass × AccelerationThis is based on Newton's Second Law of Motion which states that the force acting on an object is its mass times the acceleration of the object.Here, mass = 3000 kg and acceleration = 2 m/s²
⇒ Force = Mass × Acceleration
= 3000 × 2 = 6000 N
⇒ F = 6000 N
⇒ M = 3000 kg
⇒ a = 2 m/s²
