A cyclist accelerates uniformly from rest with an acceleration of 1.4 m 5-2 for 20 seconds. The cyclist then travels at this constant velocity for 30 seconds before decelerating uniformly to rest. The total distance travelled is 1260 metres. a) Sketch a velocity-time graph to show this information. Use the velocity-time graph to find each of the following. b) The greatest velocity of the cyclist. c) The total time taken for the journey. d) The acceleration of the cyclist during the final stage. e) Find the average speed of the cyclist during the whole journey.
