The diagram represents the straight line motion of a car. Which of the follwoing statements is true?
Correct answer: C. The car accelerates at 6 m/s2 for the first 2 s
- A. The car accelerates, stops, and reverse
- B. The car is moving for a total time of 12 s
- C. The car accelerates at 6 m/s2 for the first 2 s
- D. The car decelerates at 12 m/s2 for the last 4s
Explanation
Acceleration = slope velocity-time graph Acceleration in first 2s = 12 - 0/2 = 6 m/s2

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
