TypeDistance from velocity-time graph
DifficultyModerate -0.8 This is a straightforward M1 question testing basic understanding of velocity-time graphs. All parts involve standard procedures: finding areas under the graph (trapeziums/triangles), reading gradients, and applying definitions of average speed/velocity. No problem-solving insight required, just careful arithmetic and recall of standard formulas.

3 The diagram shows a velocity-time graph for a train as it moves on a straight horizontal track for 50 seconds. \includegraphics[max width=\textwidth, alt={}, center]{d42b2e88-74ea-486b-bb47-f512eb0c185d-3_620_1221_408_358}
  1. Find the distance that the train moves in the first 28 seconds.
  2. Calculate the total distance moved by the train during the 50 seconds.
  3. Hence calculate the average speed of the train.
  4. Find the displacement of the train from its initial position when it has been moving for 50 seconds.
  5. Hence calculate the average velocity of the train.
  6. Find the acceleration of the train in the first 18 seconds of its motion.
