When the pushing force is increased to 12 N, what is the acceleration of the block? A 0 m/s2 B 4.0 m/s2 C 6.0 m/s2 D 8.0 m/s2 5 The graph shows the total resistive force that acts on a car of mass 830 kg over a period of time. The car is at rest at t = 0 s. A constant driving force of 2500 N acts on the car from t = 2 s to t = 24 s. Which statement is incorrect? A The acceleration of the car is 3.0 m/s2 at t = 2 s. B The acceleration of the car is zero after t = 16 s. C The car is stationary from t = 0 s to t = 2 s. D The resultant force acting on the car increases from t = 2 s to t = 16 s. 6 Which of the following correctly describes an action-reaction p
