If t1 is half of t2, which of the following expressions gives the velocity of the object? (s2–s1) / t1 s2 / t2 (s2–s1) / t2 (s2–s1) / (t2–t1) 2 / 5 2) 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? 3 / 5 3) 2016 S3 EOY P1 Q07m The following displacement-time graph of an object shows the motion of an object. Take North to be the positive direction. In which direction is the object moving at 9.0 s and 15.0 s? At 9.0 s the object is moving South. At 15.0 s the object is moving North. At 9.0 s the object is moving South. At 15.0 s the object is moving South. At 9.0 s the object is moving North. At 15.0 s the object is moving North. At 9.0 s the object is moving North. At 15.0 s the object is moving South. 4 / 5 4) Object X falls freely from rest for 3 seconds and object Y also falls freely from rest for 6 seconds. Which of the following statements is correct? Y falls four times as far as X. Y falls half as far as X. Y falls three times as far as X. Y falls twice as far as X. 5 / 5 5) 2015 S3 EOY P1 Q04 A runner runs 4.0 km towards the South in 0.50 hour and 5.0 km towards the East in 1.5 hours.
