He throws a stone upwards with a velocity of 20 m s–1 at time t = 0 s. The stone reaches the top of its trajectory after 2.0 s and then falls towards the bottom of the cliff. Air resistance is negligible. Which row shows the correct velocity v and acceleration a of the stone at different times? B D C A 2 / 5 2) Which of the following is not possible? A car accelerates while moving at a constant velocity. A car has a negative acceleration and a positive velocity. A car accelerates while moving in a straight line. A car accelerates while moving at a constant speed. 3 / 5 3) Oil drips at a constant rate from a moving car. The diagram shows the pattern of the drips on a road. Which of the following statements describes the motion of the car? It accelerated and then slowed down. It moved at a steady speed and then accelerated. It accelerated and then moved at a steady speed. It moved at a steady speed and then slowed down. 4 / 5 4) 2016 S3 EOY P1 Q06 The following is a displacement-time graph for a object. What is the velocity of the object at 10.0 s? –10.0 m/s –7.0 m/s 0 m/s 7.0 m/s 5 / 5 5) 2018 S4 EOY P1 Q04 Car A is at rest in front of a traffic light. As the light turns green, Car A accelerates forward. At the exact same instant, Car B overtakes Car A at the traffic light. Both cars continue to accelerate uniformly. After T seconds, Car A catches up with Car B. Which of the following graphs best describes the motion of the two cars after passing the traffic light? Your score is Restart quiz
