TopicTravel graphs
TypeVelocity-time graph sketching
DifficultyEasy -1.3 This is a straightforward kinematics question requiring only basic understanding of velocity-time graphs and area-under-graph calculations. The motion has simple constant accelerations in three phases with all values given directly, requiring no algebraic manipulation or problem-solving insight—purely routine application of standard M1 techniques.

A cyclist starts from rest and takes 10 seconds to accelerate at a constant rate up to a speed of 15 m s\(^{-1}\). After travelling at this speed for 20 seconds, the cyclist then decelerates to rest at a constant rate over the next 5 seconds.
  1. Sketch a velocity-time graph for the motion. [3]
  2. Calculate the distance travelled by the cyclist. [3]
